Q. Solve by completing the square.g2−16g+25=0Write 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: g2−16g+25=0.
Move Constant Term: Move the constant term to the other side of the equation.Subtract 25 from both sides to isolate the g terms.g2−16g=−25
Complete the Square:Complete the square by adding the square of half the coefficient of g to both sides.The coefficient of g is −16, so half of it is −8, and the square of −8 is 64.Add 64 to both sides of the equation.g2−16g+64=−25+64g2−16g+64=39
Factor Left Side: Factor the left side of the equation.The left side is a perfect square trinomial.(g−8)2=39
Take Square Root: Take the square root of both sides of the equation.(g−8)2=±39g−8=±39
Solve for g: Solve for g by isolating the variable.Add 8 to both sides of the equation.g=8±(39)
Calculate Decimal Values: Calculate the approximate decimal values of g, rounded to the nearest hundredth.39 is approximately 6.24.g≈8+6.24 or g≈8−6.24g≈14.24 or g≈1.76
