Answer:
(6, ∞)
(-∞, 6)
Step-by-step explanation:
x^2 + 36 > 12x
Subtract 12 x from each side
x^2 -12 x+ 36 > 12x-12x
x^2 -12 x+ 36 > 0
Factor
What 2 numbers multiply together to give us 36 and add together to give us 12
-6*-6 = 36
-6+-6 = 12
(x-6) ^2 > 0
Take the square root of each side
x-6 >0 or x-6 <0
x>6 or x < 6
