Question

Answer 1

a) \(12a^2-8ab^2+4ab=4a\left(3a-2b^2+b\right)\)

b) \(4x^2-4x+1=\left(2x\right)^2-4x+1=\left(2x-1\right)^2\)

c) \(a^3-bx+ax-a^2b=a^2\left(a-b\right)+x\left(a-b\right)=\left(a-b\right)\left(a^2+x\right)\)

Answer 2

a: \(12a^2-8ab^2+4ab\)

\(=4a\left(3a-2b^2+b\right)\)

b: \(4x^2-4x+1=\left(2x-1\right)^2\)
