Solve for x.
3(x + 2) + 4(x - 5) = 10

Step-by-step explanation:

3(x+2)+4(x-5)=10

3x+6+4x-20=10

7x-14=10

7x=10+14

7x=24

x=24.

7

i mean its2

im alright what do you need

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.
