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

Answer 1

x = 6 + 3√10

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.
