Find the solution of the equation 2x² + 8x - 10 = 0 by completing the squarez?
=============================
✒️
x = 1 or x = -5
=============================
✒️
Solve By Factoring :
2x² + 8x - 10 = 0
2x² - 2x + 10x - 10 = 0
2x ( x - 1 ) + 10 ( x - 1 ) = 0
2 ( x - 1 ) ( x + 5 ) = 0
x - 1 = 0 or x + 5 = 0
x = 1 or x = -5
So the correct answer is x = 1 or x = -5

extracting square root
For , x+2 = 3
For , x+2 = -3
Therefore , the solutions are 1 and -5
