Follow the steps to solve the equationFirst, isolate a radical and then square both sides. Choose the resulting equation.

2x – 7 – 3x – 12 = 0

2x – 7 = –3x – 12

2x – 7 = 3x – 12

The result of cubing both sides of the equation is x2 – 7 = 2x + 1.This equation is

linear

quadratic

cubic

The result of setting the quadratic equation equal to 0 is x2 – 2x – 8 = 0.Choose the correct factorization of this equation.

(x – 4) (x – 2) = 0

(x – 4) (x + 2) = 0

(x – 2) (x + 4) = 0

Solve:Squaring both sides of the equation results in which of the following?

Option

Both solutions are

Only –2 is

Only 4 is

Neither solution is
