USING FORMULAR METHOD SOLVE D EQUATION(M-3)²=121

M-3=±11

M₁₂=14
M₂ =-8

(m - 3)² = 121

To solve the equation (M-3)² = 121 using the formula method, we can follow these steps:

Step 1: Rewrite the equation in its quadratic form.

(M - 3)² = 121

Step 2: Take the square root of both sides of the equation.

√((M - 3)²) = √121

M - 3 = ±11

Step 3: Solve for M.

For M - 3 = 11:
Add 3 to both sides of the equation.
M - 3 + 3 = 11 + 3
M = 14

For M - 3 = -11:
Add 3 to both sides of the equation.
M - 3 + 3 = -11 + 3
M = -8

Therefore, the solutions for the equation (M-3)² = 121 are M = 14 and M = -8.
