Answer:

A

Step-by-step explanation:

Use foil to expand it.

y = 4 (x^2 + 7x - 9x - 63)     Combine the like terms on the right.

y = 4(x^2 - 2x - 63)              Use the distributive property to remove the brackets.

y = 4x^2 - 8x - 4*63            Combine the two multiplied factors on the right.

y = 4x^2 - 8x - 252              4* 63 = 252

The answer is A
