**Algebra**

The factor theorem states that a polynomial f(x) has a factor (x − k) if and only if f(k) = 0. So if (x+2) is a factor of P(x), then P(-2)=0. Since P(-2)= 21, it is clear that (x+2) is not a factor of P(x)=2x^4+x^3-3x-9.

Sorry, the last paragraph is not clear. If f(a0)=0, then (x-a0) is a factor of f(a). So check and see which of f(1),f(2)...=0 and hence find a rational factor of f(a). If f(-1)=0, then (a+1) is a factor. Do a long division and factor the remaining quadratic.

look for a common factor of 10 and 6,, for example if you have 6/4, 6 and 4 have a common factor of 2, thus you can factor out 2 from both: 2*3 / 2*2 = 3/2 like that. try it to -10/6 ~ :)

Changing the loop from a circle to a square will multiply its area by a factor pi/4. The induced voltage will be multiplied by that factor. Since the wire resistance will remain unchanged, the induced current will also be multiplied by a pi/4 factor.

If it is in factored form, it should have a common factor for the whole expression. (4x+5) is not a factor for the whole expression, just the first term (before the + sign). To factor "completely", we need to expand the expression, collect similar terms and factor from there...

**Advanced Math**

If b is an integer factor of b, and b is an integer factor of x, then b = ma and c = nb, where m and n are both integers. It follows that c = m n a. Since m and n are both integers, so is mn. Therefore a is an integer factor of c, or, in other words, "a divides c".

Since x is a known factor, you will have to divide each term in the binomial by the known factor to get the other factor. 7x²/x = 7x x/x = 1 So 7x²+x = x(7x+1)

to get the greatest common factor, we first find the factors of each number (we call it a factor of a certain number if that certain number is divisible by the factor or it gives zero remainder when divided by the factor),, for example, 10 has factors 1, 2, 5 and 10, because ...

Since the force is k/r^2 Then if r is multiplied by a factor of a, the new force is k/(ar)^2 = k/r^2 / a^2 So, you have multiplied the distance r by a factor of 23/6. Consequently, the force is reduced by a factor of (23/6)^2.
