Answer:
x = -6, 6
Step-by-step explanation:
Isolate the variable, x. Find factors of all terms on the left:
x² + 36 = 0
x 6
x 6
(x + 6)(x + 6) = 0
Solve for x:
(x + 6) = 0
x + 6 = 0
x + 6 (-6) = 0 (-6)
x = -6
x² + 36 = 0
x -6
x -6
(x - 6)(x - 6) = 0
Solve for x:
x - 6 = 0
x - 6 (+6) = 0 (+6)
x = 6
x = -6 , 6.
