X2 + 3X - 18 Ask yourself, what two factors of - 18 add to 3? (X + 6)(X - 3) -----------------

3(x+2) = x -18 3x+6 = x -18 3x -x = -18 -6 2x = -24 x = -12

x^2 + 18 = 9x x^2 - 9x + 18 = 0 (x )(x ) Since 6 * 3 = 18 and 6 + 3 = 9, (x 3)(x 6) Since the 18 is positive, the factors are either both positive or both negative. Since the 9 is negative, they must both be negative. (x - 3)(x - 6)

The answer to this question is 18. This is a math problem.

You add -18... 18 + y = 32 18 + y + (-18) = 32 + (-18) y = 14

5x squared plus 33x plus 18 = (5x + 3)(x + 6) x = -6, -3/5

That factors to (x - 3)(x + 6)

Since the problem has 4 terms, first you factor x cubed plus 9x squared, then you factor 2x plus 18. So when you factor the first two term, you would get x sqaured (x plus 9). Then when you factor the last two terms and you get 2 (x plus 9). Ypure final answer would be (x squared plus 2)(x plus 9)

If that's -18y2, the answer is (3x - 2y)(x + 9y)

0 = 2m^2 - 2m + 36 0 = 2(m^2 - m + 18) 0 = m^2 - m + 18

2(x - 3)(x - 3)

I'm not sure this was notated correctly. As written, this is -11x plus or minus 18, which doesn't factor.

12 squared plus 18 squared is equal to 468.
