Solve 3(x + 2) > x
{x | x < -1}
{x | x > -1}
{x | x < -3}
{x | x > -3}

{x | x > -3}

Step-by-step explanation:

3 (x+2) > x

Distribute

3x+6 >x

Subtract 3x from each side

3x-3x+6 >x-3x

6 > -2x

Divide each side by -2, remembering to flip the inequality

6/-2 < -2x/-2

-3 < x

{x | x > -3}

Step-by-step explanation:

3(x + 2) > x

3x + 6 > x

2x > -6

x > -3

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.
