Twice the sum of a number and 4 is equal to three times the difference of the number and 2

2(n+4)=3(n-2) is your equation. Hope that was what you were looking for.

Let the number be x, then:-

2(x + 4) = 3(x - 2)

2x + 8 = 3x - 6

14 = x

Answer x = 14

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.
