Question

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

x=6+3/10
O x=6+2.17
| O x= 12+3/22
x= 12+3/10

Answer 1

x = 6 ± 3√10

Explanation:

Since this is an unfactorable expression, apply the Quadratic Formula, -b ± √b² - 4ac\2a, according to the Quadratic Equation, y = Ax² + Bx + C. Applying the Quadratic Formula will give you the above answer.

NOTE: -b = OPPOSITE of b
