x=1

Step-by-step explanation:

x=1

Step-by-step explanation:

Ok so I don't like using tiles but thats just me. So I'm going to explain using just the equation.

So 2x - 3 = -1

You need to isolate x to find out what x is.

To do this lets get rid of the -3.

To get rid of it you have to use the opposite operation (+/-) to both sides.

2x - 3 (+3) = -1 (+3)

-3 + 3 is 0 meaning 2x is alone which is what we need.

2x = 2

Now you need to divide the 2 from both sides to fully isolate x.

2x (/2) = 2 (/2)

x = 1

Your answer will be 1

Don't be afraid to reach out if you need further help! I hope this helps!

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.
