4xy+4x-6y-6 factored completely

(4x - 6)(y + 1)

Step-by-step explanation:

Group them: (4xy + 4x) (-6y - 6)

Take out the greatest common factor for both:

4x(y + 1)  -6(y + 1)

Put it together: (4x - 6) (y + 1) (y + 1)

Since there are two (y + 1)'s, you can get rid of one, giving you:

(4x - 6) (y + 1)

idk bring the function back   im not smart

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.
