Solve by:

Completing the square

Quadratic formula

Factoring method

One step at a time

x²−x−18=12

Move 18 to the right side

x²−x=30

Rewrite in the form (x+a)²=b

(x−12 )²=1214

For f ²(x)=a the solutions are f(x)=√a, −√a

Solve x−12 =√1214 : x=6

Solve x−12 =−√1214 : x=−5

The solutions to the quadratic equation are:

x=6, x=−5
