No matter how hard I try I can not figure out how to factor this: 4a^2-32a+63. Any help please? Thanks so much. Please explain the steps!

Question

anonymous · Answer

(2 a-9) (2 a-7)

anonymous · Answer

So take the coefficient on the a squared term and multiply that to 63 you need to find two number (we will call them A and B) such that A * B = 4 * 63 and A + B = -32

anonymous · Answer

you do this with other polynomials but the coefficient on the squared term is usually a 1so most people don't teach it that way.
