Question

Factor completely −5x2 + 10x − 15. −5(x2 − 2x + 3) −1(x2 − 10x + 15) −5x(x2 − 2x + 3) −5(x2 − 2x − 3)

Answer 1

-5(x² -2x +3) your welcome

Explanation:

Answer 2

-5(x² -2x +3)

Explanation:

5 is a factor common to all of the coefficients. It is convenient to have the x² coefficient be positive in the factored form, so the result of factoring out -5 is ...

... -5((-5x²/-5) +(10x/-5) +(-15/-5)) = -5(x² -2x +3)
