Solve for x in the equation X2 - 12x+36-90

X = 6+3/10

X=6+2V7

X = 12+3 22

x = 12+3/10

x = 6 + 3√10

Step-by-step explanation:

Since this is an unfactorable expression, we need to apply the Quadratic Formula, - b ± √b² - 4ac/2a [radical wrapped around b² - 4ac]. Evaluate, then you will end up with the answer above.
