Q. Solve by completing the square.g2−4g−49=0Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.g= _____ or g= _____
Rewrite Equation: Rewrite the equation in the form of g2+bg=c. Add 49 to both sides to move the constant term to the right side of the equation. g2−4g−49+49=0+49g2−4g=49
Complete the Square:Complete the square by adding the square of half the coefficient of g to both sides.Since (−4/2)2=4, add 4 to both sides.g2−4g+4=49+4g2−4g+4=53
Factor Left Side: Factor the left side of the equation.g2−4g+4 can be factored into (g−2)2.(g−2)2=53
Take Square Root: Take the square root of both sides of the equation.(g−2)2=±53g−2=±53
Solve for g: Solve for g by adding 2 to both sides of the equation.g−2+2=±53+2g=2±53
Calculate Approximate Values: Calculate the approximate values of g, rounding to the nearest hundredth.g≈2+53 or g≈2−53g≈2+7.28 or g≈2−7.28g≈9.28 or g≈−5.28
