Q. Solve by completing the square.m2+12m−23=0Write 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−23=0. We want to complete the square for the left side of the equation. First, move the constant term to the right side by adding 23 to both sides. m2+12m=23
Complete the Square: To complete the square, we need to add (212)2 to both sides of the equation.(212)2=62=36So we add 36 to both sides:m2+12m+36=23+36m2+12m+36=59
Factor Perfect Square Trinomial: Now, factor the left side of the equation which is a perfect square trinomial. (m+6)2=59
Take Square Root: Take the square root of both sides of the equation to solve for m.(m+6)2=±59m+6=±59
Isolate Variable: Isolate m by subtracting 6 from both sides of the equation.m=−6±59
Calculate Approximate Values: Calculate the approximate decimal values of m by taking the square root of 59 and rounding to the nearest hundredth.59≈7.68So we have:m≈−6+7.68 or m≈−6−7.68m≈1.68 or m≈−13.68
