The product is: x^2 +8x +16
-1
Their product.
It is: 8x^2 +68x +32
X^2-4
(4 x 4) + (4 x 9) = 4 x 13 = 52
(4 x 11) + (4 x 25) = 4 x 36 = 144
4(x+y)
It is the parabolic function defined by the product (x+1)(x+5), with x intercepts at -1 and -5, y-intercept at (0,5) and a vertex at (-3, -4).
Special product and factoring
(x + 4) + (x + 5) = 2x + 9
x/(x + 4) = 4/(x + 4) + 2 (x - 4)/(x + 4) = 2 x - 4 = 2x + 8 -x = 12 x = -12
