5x² + 10x -7 = 0
x² + 10/5 x - 7/5 = 0
x² +2x = 7/5
x² + 2x +1 = 1+7/5
(x +1)² = 12/5
take square root both sides
x + 1 = ± 2√3/√5
x = -1 ± 2√3/√5
=( -√5 ±2√3)/√5
x² + 10/5 x - 7/5 = 0
x² +2x = 7/5
x² + 2x +1 = 1+7/5
(x +1)² = 12/5
take square root both sides
x + 1 = ± 2√3/√5
x = -1 ± 2√3/√5
=( -√5 ±2√3)/√5
