Solve for v where v is a real number If there is more than o

Solve for v, where v is a real number. (If there is more than one solution, separate them with commas.)

Solution

(-v +6) = v

squaring on both sides

==> -v +6 = v²

==> v² + v -6 = 0

==> v² + 3v - 2v - 6 = 0

==> v(v +3) -2(v +3) = 0

==> (v +3)(v -2) = 0

==> v = -3 , 2
