Use distributive property.
X/Y (X^3Y/Y^-1 + Y^3X/X^3Y

4x + 4y + 12

Step-by-step explanation:

x + 3y − y + 3x + 2(2 + 4 + y)

Apply Distributive Property:

2(2 + 4 + y)

2*2=4

2*4=8

2*y = 2y

x + 3y − y + 3x + 4 + 8 + 2y

Combine Like Terms:

x + 3x +2y +3y - y + 4 + 8

4x + 4y + 12

17   x 256=4352

sorry if this is wrong, i'm new.

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.
