Question

X^3 - 11x^2 + 30x

Answer 1

\(x^3-11x^2+30x\)

\(=x\left(x^2-11x+30\right)\)

\(=x\left(x^2-5x-6x+30\right)\)

\(=x\left[x\left(x-5\right)-6\left(x-5\right)\right]\)

\(=x\left(x-5\right)\left(x-6\right)\)

 

Answer 2

x³-11x²+30x

=x(x²-11x+30)

=x(x²-6x-5x+30)

=x[x(x-6)-5(x-6)]

=x(x-5)(x-6)
