That would be
f(x) = (x - 2)(x - 3)(x + 3)

expanded this is f(x) = (x - 2)(x^2 - 9)
= x^3 - 2x^2 - 9x + 18

Solve for x (-4/3) x - 6 = -26 A. −27 B. −15 C. 15 D. 27

andre [41]

$- \dfrac{4}{3} x - 6 = -26$

//Add 6 to both sides:
$- \dfrac{4}{3} x = -20$

//Multiply by -1 on both sides:
$\dfrac{4}{3} x = 20$

Multiply by 3 on both sides:
$4x = 60$

Divide by 4 on both sides:
$x = 15$
