(A) 10, 24, and 26
(B) 7, 24, and 25
(C) 3, 4, and 15
(D) 6, 8, and 10

step-by-step explanation: yes

x

step-by-step explanation:

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.

just keep asking questions until you have a better understanding.
