Q. Solve by completing the square.s2+18s=−29Write 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+18s=−29.
Move Constant Term: Move the constant term to the other side of the equation.Add 29 to both sides to isolate the s2 and s terms.s2+18s+29=0+29s2+18s=29
Find Completing Square Number: Find the number to complete the square.Take half of the coefficient of s, square it, and add it to both sides of the equation.(18/2)2=92=81s2+18s+81=29+81s2+18s+81=110
Factor Left Side: Factor the left side of the equation.The left side is now a perfect square trinomial.(s+9)2=110
Take Square Root: Take the square root of both sides of the equation.(s+9)2=±110s+9=±110
Solve for s: Solve for s.Subtract 9 from both sides to isolate s.s=−9±110
Simplify Square Root: Simplify the square root if necessary and round to the nearest hundredth.110≈10.49s=−9±10.49s≈−9+10.49 or s≈−9−10.49s≈1.49 or s≈−19.49
