1 . If 5x + 2 = 6 x + 2 How many solutions does this equation have?

2. If 7x + 2 = 7(x + 2)
How many solutions does this equation have?

one solution x=0

Step-by-step explanation:

1.6-5=1 or x, 2-2=0

2.same thing x=0,7divided by 7 = 1 or x 2-2 =0

NUMBER one have ons solution equal zero

NUMBER tow don't have any solution

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.
