A)5x−7=5x

B)3x−9=3(x−3)

C)2x−6=−2(x−3)

D)2x+6−5x=−3(x−2)

are you in algebra 1? i have trouble on this to, try simplifying both sides of the equation as best as you can, maybe that could help

4x and 6y

im not sure though

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.
