5. factor the expression: y2 + 6y – 16 a. (y – 8)(y + 2) b. (y + 8)(y – 2) c. (y + 4)(y + 4) d. (y + 4)(y – 4)

For this case we have the following polynomial:

We must find two numbers that comply with:

1) The algebraic sum of the numbers is equal to 6.

2) The multiplication of the numbers is equal to -16.

Therefore, factoring the polynomial we have:

The factored expression is:

b. (y + 8) (y - 2)

point a is the center of this circle.

the ratio of the lengths of (ef/bc) and (ad/ih) is 2: 1.
