Thread: factorization.

factorize:
D(x)=x^2-20x+100-2(10-x)(x+1).

f(x)=(2x-6)(2x-1)+4-x^2.

a(x)=(2x-3)(x+5)-4x^2+9.

thnx...

thnx...

first things first foil the brackets and collect like terms...

ya i knew..
but,
d(x)=(x-10)^2-2(10-x)(x+1).
and,
f(x)=(2x-6)(2x-1)+(2-x)(2=x)
and i didn't get a(x).

Hi
