Question

Answer 1

\(a,=a^2+2a+1\\ b,=x^2+x+\dfrac{1}{4}\\ c,=x^2-2x+1\\ d,=16-8a+a^2\\ e,=a^3+3a^2+3a+1\\ f,=x^2-6x+9\\ =x^3-3x^2+3x-1\\ h,=\left(x-5\right)\left(x+5\right)\)

Answer 2

a) \(=a^2+2a+1\)

b) \(=x^2+x+\dfrac{1}{4}\)

c) \(=x^2-2x+1\)

d) \(=16-8a+a^2\)

e) \(=a^3+3a^2+3a+1\)

f) \(=x^3-9x^2+27x-27\)

\(\left(x-1\right)^3=x^3-3x^2+3x-1\)

g) \(=\left(x-5\right)\left(x+5\right)\)
