Question

What is the factored from of y2+6y-16

Answer 1

(y-2)(y+8) Is the answer because if you think about what two number add up to 6 and multiply to -16 it’s -2 and 8


Answer is (y-2)(y+8)

Answer 2

(y + 8)(y - 2)

Explanation:

Given

y² + 6y - 16

Consider the factors of the constant term (- 16) which sum to give the coefficient of the y- term (+ 6)

The factors are + 8 and - 2, since

8 × - 2 = - 16 and 8 - 2 = 6, thus

y² + 6y - 16 = (y + 8)(y - 2)
