What are the coefficient(s) in the following expression? 5a + 6b-7c
O 5, 6, 7
O 5, 6, -7
oa, b, c
o 4

5 , 6 , -7 yeah thats it :

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.

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.
