Question

I need to know what is the result of x^2-6x-72, step by step answer..

Answer 1

Answer:(x+6)*(x-12)

Step-by-step explanation:

1. x^2-6x-72: write -6x as a difference -----> x^2+6x-12x-72

    2. x^2+6x-12x-72: Factor out x from the expression-----> x*(x+6)-12x-72:

    Factor our -12 from the expression-----> x*(x+6)-12(x+6)

   3. x×(x+6)-12(x+6): Factor out x+6 from the expression.----> (x+6) * (x-12)
