2.8 times the number q is 11.76. which equation shows the relationship between 2.8, 11.76, and q and then find the value of q? a. q2.8=11.76q2.8=11.76 b. q = 32.928 2.8q = 11.76 q = 4.2 c. q + 2.8 = 11.76 q = 8.96 d. 11.76q = 2.8 q = 0.24

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.
