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.
