Can Someone Evaluate This

Explanation:

Replace x with 4. Then use PEMDAS to simplify fully.

When using PEMDAS, we evaluate the stuff in the parenthesis first. Afterward we divide.

the correct answer is 45x

9×5=45 then add the x

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
