Algebra (test corrections)
This problem was on a test and I got it wrong, and if I do it over I get half the credit back, but I need help with it plz. (11x^2+2x^3+14+17x)/(2x+5) My algebra teacher didn't even go over this lesson (we skipped it) and it was on the test. She says it's long division, but I ...

Why are variables useful in algebra? I feel the use of variables make it difficult for many people to understand because it is subconcious that math is numbers, not letters.... Thank you! By using a variable, one may make use of a formula which is good for hundreds of ...

I am getting ready to start an Algebra class for the first time and I was wondering what challenges people have with learning and using algebra concepts. Also what are the best ways to over come math anxiety? The best way? Learn the language of algebra.

I need help with my daughters homework. I know a little bit of algebra but it has been about 15 years since I have done it. She switched schools recently and there was a learning gap in the schools. The problem is: give the demensions of rectangles with the perimeters of 70 ...

Solve for s in this equation. Depreciation. D=C-s/n This is my answer D-C=C-s/n-c D-C=-s/n -n(D-C)=-s/n*(-n) -nD+nC=s s=n(C-D) Please chack to see if this is correct Looks fine to me. A slightly shorter (by 2 lines) rearragement is: D=C-s/n D+s/n=C s/n=C-D s=n(C-D) but hey, ...

Algebra, Solving equations
I'm stuck with this equation: y = (4x-1)/(2x+3) We're working on inverses, which I understand, but my mind is blanking on how to solve this for x. Thanks in advance, Amy :) after you interchanged the x and y variables, and expanded you should have had x = 8y^2 + 10y - 3 ...

how do I convert 9/16 into a percent? Is this done differently in a algebric form? Divide 16 into 9.000, using the normal procedures of long division. This should give you 0.5625; then multiply the decimal by 100. This isn't algebra, by the way.

Solve the polynomial 40x^2+2x-65 Notice that for x = 1 the value is -23. The number 23 is a prime number and the only factors are thus 23 and 1 up to signs. So, you can simply the search for the factors of the polynomial a great deal by substituting: x = 1 + t which yields 40 ...

Find the vertex of the functions given below. 1. y=(x-4)(x+2) 2. y=2x^2-4x+1 The midpoint of the x-intercepts of a parabola has the same x value as the vertex. the x-intercepts are obviously x=4 and x=-2 so the x value of the vertex is...... sub that back into the equation to ...

what is the value of (n) ? (n+3)! = 5040 the prime factorization of 5040 = 2x2x2x2x3x3x5x7 since the ! function involves the multiplication of consecutive integers, it makes sense to arrange these factors so they form consecutive numbers. I got 2,3,4,5,6, and 7 and sure ...

How can you solve algebra equations? The idea is to find a way to isolate the unknown by itself. You can add, subtract, multiply, and divide both </s> sides of the equal signs to do that.

Find the discriminant and solutions for the following equations. #1) 9x^2+6x+1=0 #2) -2x^2+3x-2+0 I will be happy to critique your work. what is b^2-4ac? #1) 9^2-4(6)(1)= 81-4(6)= 81-24=57 so then 57 is the solution but what is the discriminant or is 57 the discriminant? #2) -...

solve the polynomial y=2x^2-4x+1 For Further Reading algebra - Reiny, Thursday, May 17, 2007 at 10:34pm I am sure neither your text nor your teacher asked you to "solve the polynomial y=2x^2-4x+1 " are you graphing the function, or are you solving the quadratic y=2x^2-4x+1 ? I...
