Please help i don’t understand

Step-by-step explanation:

f(x) = x³ − 8x² − 12x + 96

Factor by grouping:

f(x) = x² (x − 8) − 12 (x − 8)

f(x) = (x² − 12) (x − 8)

f(x) = (x + √12) (x − √12) (x − 8)

f(x) = (x + 2√3) (x − 2√3) (x − 8)

The roots are ±2√3 and 8.

step-by-step explanation:

if x = 2 you have to find x to finish the problem

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
