Solve 5x - (2x + 2) = x + (3x + 5) (make sure to type the number only)

7

Step-by-step explanation:

To solve this problem we need to find x

First we need to do parenthesis

This means that the equation becomes 5x - 2x - 2 = x + 3x + 5

Next add or subtract, this simplifies it to 3x - 2= 4x + 5

After this bring the numbers on the right and the variables on the left

This means subtracting 4 on each side and adding 2 on each side

Now the equation becomes -x = 7

Lastly, put the negative on the right

x = 7

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.
