Use the zero product property to find the solutions to the equation x2 – x – 6 = 0.

Ahat [919]

we know that

The Zero Product Property states that if $a*b = 0$ , then either $a = 0$ or $b = 0$ (or both)

we have

$x^{2} -x-6=0$

rewrite the expression

$x^{2} -x-6=(x+3)(x-2)$

$(x+3)(x-2)=0$

$(x+3)=0\\x=-3$

$(x-2)=0\\x=2$

therefore

<u>the answer is the option</u>

x = –3 or x = 2
