Question

What is the completely factored form of the quadratic expression 3x^2-30x-72

Answer 1

Explanation:

have a good one

Answer 2

Given the expression below

`3x^2-30x-72`

Factorizing the expression gives

`\begin{gathered} Factor\text{ out 3} \\ =3\left(x^2-10x-24\right) \\ =3(x^2-12x+2x-24) \\ =3(x(x-12)+2(x-12)) \\ =3\left(x+2\right)\left(x-12\right) \end{gathered}`

Hence, the completely factored form of the quadratic expression is

`3\left(x+2\right)\left(x-12\right)`
