Q. Solve by completing the square.g2+2g=47Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.g= _____ or g= _____
Write Equation Form: Write the equation in the form of g2+bg=c. The given equation is already in this form: g2+2g=47.
Move Constant Term: Move the constant term to the right side of the equation.Subtract 47 from both sides to isolate the g terms.g2+2g−47=0g2+2g=47
Complete the Square:Complete the square by adding the square of half the coefficient of g to both sides.The coefficient of g is 2, so half of it is 1. The square of 1 is 1.Add 1 to both sides of the equation.g2+2g+1=47+1g2+2g+1=48
Factor Left Side: Factor the left side of the equation.The left side is a perfect square trinomial.(g+1)2=48
Take Square Root: Take the square root of both sides of the equation.(g+1)2=±48g+1=±48
Simplify Square Root: Simplify the square root of 48.48 can be simplified to 16×3 which is 43.g+1=±43
Isolate Variable: Isolate g by subtracting 1 from both sides.g=−1±43
Calculate Approximate Values: Calculate the approximate decimal values of g.43 is approximately 6.93 (rounded to the nearest hundredth).g≈−1+6.93 or g≈−1−6.93g≈5.93 or g≈−7.93
