3.48683298

The correct answer is A. x = 6 + 3 √10 Step-by-step explanation: Let’s solve for x: x² – 12x + 36 = 90 Factoring this quadratic equation, we have: (x – 6) (x – 6) = 90 (x – 6)² = 90 x – 6 = √90 (Square root to both sides of the equation) x = 6 + √90 (Adding 6 to both sides of the equation) x = 6 + √9 * 10 x = 6 + √3² * 10 x = 6 + 3 √10 The correct answer is A. x = 6 + 3 √10

Trinomial cannot be factored.
