Question

what is one zero of the function $f(x) = (2x - 4)(x + 3)$? type your answer in the box.

Explanation:

Step1: Set function equal to 0

$f(x) = (2x-4)(x+3) = 0$

Step2: Solve first factor for x

$2x-4=0 \implies 2x=4 \implies x=\frac{4}{2}=2$

Step3: Solve second factor for x

$x+3=0 \implies x=-3$

Answer:

$2$ (or $-3$ is also a valid answer)
