Q. Solve by completing the square.h2+14h=13Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.h= _____ or h= _____
Rewrite Equation: Rewrite the equation in the form of h2+bh=c. We have the equation h2+14h=13. To complete the square, we need to move the constant term to the other side of the equation. Subtract 13 from both sides. h2+14h−13=0h2+14h=13
Move Constant Term: Choose the number to add to both sides to complete the square.Since (214)2=49, we add 49 to both sides.h2+14h+49=13+49h2+14h+49=62
Complete the Square: Factor the left side of the equation.The left side is now a perfect square trinomial.(h+7)2=62
Factor Left Side: Take the square root of both sides of the equation.(h+7)2=±62h+7=±62
Take Square Root: Solve for h.Subtract 7 from both sides to isolate h.h=−7±62
Solve for h: Simplify the square root and round to the nearest hundredth if necessary.62 is approximately 7.87 (rounded to the nearest hundredth).h=−7±7.87
Simplify Square Root: Find the two values of h.h=−7+7.87 implies h≈0.87.h=−7−7.87 implies h≈−14.87.Values of h: 0.87, −14.87
