Q. Solve by completing the square.s2+16s=47Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.s=_____ or s=_____
Write Equation Form: Write the equation in the form of s2+bs=c. The given equation is already in this form: s2+16s=47.
Complete the Square: Add the square of half the coefficient of s to both sides to complete the square.The coefficient of s is 16, so half of it is 8, and the square of 8 is 64.Add 64 to both sides of the equation:s2+16s+64=47+64s2+16s+64=111
Factor Left Side: Factor the left side of the equation.The left side is a perfect square trinomial:(s+8)2=111
Take Square Root: Take the square root of both sides of the equation.(s+8)2=±111s+8=±111
Solve for s: Solve for s by isolating the variable.Subtract 8 from both sides of the equation:s=−8±111
Approximate and Solve: Approximate the square root of 111 to the nearest hundredth and solve for s.111≈10.54s≈−8±10.54s≈−8+10.54 or s≈−8−10.54s≈2.54 or s≈−18.54
