What are the solutions to the equation x2 6x 40
Asked by maham237 @ in Mathematics viewed by 432 People
x2 + 6x = 40
Answered by maham237 @
X² + 6x = 40
Subtract 40 from both sides:
x² + 6x - 40 = 40 - 40
refine: x² + 6x - 40 = 0
factor x² + 6x - 40 = 0
( x- 4 ) ( x + 10 ) = 0
solve x - 4 = 0
x = 0 + 4
x = 4
solve x + 10 = 0
x = 0 - 10
x = - 10
solution : x = 4 , x = - 10
hope this helps!
