Factor the expression.

x2 + 8x + 16

x² + 3x + 16 =

Answer: 17x^2 + 11x + 16

Step-by-step explanation:

The first term is, 17x^2 its coefficient is 17.

The middle term is, + 11x its coefficient is 11.

The last term, "the constant", is + 16

Step-1 : Multiply the coefficient of the first term by the constant 17 • 16 = 272

Step-2 : Find two factors of 272 whose sum equals the coefficient of the middle term, which is 11.

-272 + - 1 = - 273

-136 + - 2 = - 138

-68 + - 4 = - 72

-34 + - 8 = - 42

-17 + - 16 = - 33

-16 + - 17 = - 33
