Q. Solve by completing the square.s2+24s=−47Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.s= _____ or s= _____
Write equation in form: Write the equation in the form of s2+bs=c. The given equation is already in this form: s2+24s=−47.
Move constant term: Move the constant term to the right side of the equation.Add 47 to both sides to isolate the s2 and s terms on the left side.s2+24s+47=0+47s2+24s=47
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.(24/2)2=122=144s2+24s+144=47+144s2+24s+144=191
Factor left side: Factor the left side of the equation.The left side is now a perfect square trinomial.(s+12)2=191
Take square root: Take the square root of both sides of the equation.(s+12)2=±191s+12=±191
Solve for s: Solve for s.Subtract 12 from both sides to isolate s.s=−12±191
Calculate approximate decimal values: Calculate the approximate decimal values of s.191≈13.82 (rounded to the nearest hundredth)s≈−12+13.82 or s≈−12−13.82s≈1.82 or s≈−25.82
