Q. Solve by completing the square.m2+12m=−13Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.m= _____ or m= _____
Move Constant Term: Start with the equation m2+12m=−13. To complete the square, we need to move the constant term to the right side of the equation. m2+12m+__=−13+__
Find Completing Number: Find the number to complete the square.The coefficient of m is 12, so we take half of it, which is 6, and then square it to get 36.m2+12m+36=−13+36
Add 36: Add 36 to both sides of the equation.m2+12m+36=23Now the left side of the equation is a perfect square trinomial.
Factor Left Side: Factor the left side of the equation.(m+6)2=23
Take Square Root: Take the square root of both sides of the equation.(m+6)2=±23m+6=±23
Solve for m: Solve for m by subtracting 6 from both sides.m=−6±23
Calculate Approximate Values: Calculate the approximate decimal values of m, rounding to the nearest hundredth.m≈−6+23 and m≈−6−23m≈−6+4.80 and m≈−6−4.80m≈−1.20 and m≈−10.80
