Question

Answer 1

\(a,=3x^2-6x-5x+5x^2-8x^2+24=24-11x\\ b,=x^2+10x+25-x^2+9=10x+34\\ c,=x^3-25x-x^3-8=-25x-8\\ d,=x^3+x^2+x-x^3-x^2-x+5=5\)

Answer 2

a) \(=3x^2-6x-5x+5x^2-8x^2+24=-11x+24\)

b) \(=x^2+10x+25-x^2+9=10x+34\)

c) \(=x^3-25x-x^3-8=-25x-8\)

d) \(=x^3+x^2+x-x^3-x^2-x+5=5\)

Answer 3

a: \(=3x^2-6x-5x+5x^2-8x^2+24=-9x+24\)

b: \(=x^2+10x+25-x^2+9=10x+34\)
