How to solve X^2+36=0
ICE Princess25 [194]

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.
