What is the basic principle that can be used to simplify a polynomial? What is the relevance of the order of operations in simplifying a polynomial? The basic principle is to remove common factors. Mathematics is a language, and has rules. The order of operations is one of the...

HELP!! This has me stumped! x^2-4y^2-4x+4

can this equation be factored further? y= x^4+2x^3+4x^2+8x+16 Not in the real number system. If you plot the function, you will see the minimum is at x=-1.1 (approx) and y is positive. At no x does the function equal zero, so there are no real roots, which means, no factors. ...

first question: could x^5-1 simplified? what is the limit of cuberoot(x^2-5x-4) as x approaches 4? For the first one: could x^5-1 simplified? Yes, the expression can be factored as the 5th roots of unity. First, divide it by (x-1) to get (x^5-1)=(x-1)*4th deg poly. I'm not ...

the limit of cuberoot((-3x^3+5x+2)/(x^2-1)) as x approaches 3 is the problem. how could (-3x^3+5x+2) so it would be factored out with denominator? thanks! If you read the answer I gave for the previous question, then you can take the limit inside to get lim x->3 of((-3x^3+...

Roots Ok, what about roots? Roots of polynomials? Square roots? Cube roots? Terminology, notation, equations using them? Help us out here a little.

The roots of the eqn, x^4 + px^3 + qx^2 + rx + s = 0 where p, q, r, s are constants and s does not equal to 0, are a, b, c, d. (i) a^2 + b^2 + c^2 + d^2 = p^2 -2q (in terms of p & q) (ii) 1/a + 1/b + 1/c + 1/d = -r/s (in terms of r & s) (iii) using the above results, or ...

1/3x + 5/6 = 2/9x - 1/3 How do I solve this to get the answer? For basic algebra you need to understand that we can add (or subtract) the same quantity from both sides without affecting the = sign. We can also multiply and divide (except by 0) both sides without affecting the...

express this in binomial: 2 4ez (4e-z) the 2 is the square.. can anyone teach me how to do this??? I'm a little unsure what your question is asking for here. Ordinarily, a binomial is an expression with two variables and some positive power, e.g. (x+y)^2 or (x+y)^3 are ...

3 dimensional shapes What about them? Do you need examples? A sphere is one. You can think of others. 3D shapes are figures that pop out. Like for example, if you saw an airplane fly by your're seeing it in 3D. But if you see an airplane on a piece of paper drawn by a third ...

The book says: Find three different values that complete the expression so that the trinomial can be factored into the product of two binomials. Factor your trinomials. 4g^2+___g+10 Okay, I tried Hotmath, but it didn't explain ALL the steps. I just simply COULD NOT figure it ...

Do you know how to do synthetic or long division of polynomials? The basic idea is that you can find zeroes which would tell you where the x intercepts of the graph are. Trust me this far: Always put the right side of the equals sign in descending order of exponents (cubed ...

History of Polynomials. I need to know how polynomials was created. I search for it on google but I can't find the right one.

Polynomials are a natural outgrowth of algebra. Algebra was introduced by the Babylonians about 4000 years ago. It was later refined independently by the Indian Brahmagupta and the Muslim Al-Khwarizmi. Somewhere in their writing they probably considered polynomials, but the ...

px^3 + qx^2 - 5x +84 = (x-7)(x-4)(ax-b) = ax^3 - (11a+b)x^2 + (28a+11b)x - 28b If the polynomials are identical, then p = a q = -(11a+b) -5 = 28a+11b 84 = -28b So, b = -3 a = 1 p = 1 q = -(11-3) = -8 and the polynomial is x^3 - 8x^2 - 5x + 84 = (x-7)(x-4)(x+3)

polynomials am i doing it right?
because you see that when you expanded the polynomials after the -2x^4 yu have a - instead of a positive because recall that when the brackets expand - and - = +. That is the only thing you did wrong. Good luck! you are on the right track though.

Steve it is a polynomials product it is asking me for the sum the difference and the product for this problem X -1 : X-2 I do not know how to do this as we just started this today thank you sir

what does the ":" mean? If it just separates two polynomials, then if we call them f(x) and g(x), f+g = x^3 + x^2 + 2x - 2 f-g = -x^3 + 3x^2 - 2x f*g = 2x^5 - 2x^4 + 3x^3 - x^2 - 2x + 1

Hey, Terrence. As I said before, what does the ":" mean? If it just separates two polynomials, then if we call them f(x) and g(x), f+g = x^3 + x^2 + 2x - 2 f-g = -x^3 + 3x^2 - 2x f*g = 2x^5 - 2x^4 + 3x^3 - x^2 - 2x + 1
