Q. Solve by completing the square.j2−26j=−27Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.j= _____ or j= _____
Rewrite equation: Rewrite the equation in the form of j2+bj=c. Add 27 to both sides to set the equation to zero. j2−26j+27=0
Complete the square: Choose the equation after completing the square.Since (−226)2=169, add 169 to both sides to complete the square.j2−26j+169=27+169j2−26j+169=196
Factor left side: Identify the equation after factoring the left side.j2−26j+169=196(j−13)2=196
Take square root: Identify the equation after taking the square root on both sides.Take the square root of both sides of the equation.(j−13)2=196j−13=±196j−13=±14
Isolate variable: Choose the equation after isolating the variable j. To isolate j, add 13 to both sides of the equation. j−13+13=±14+13j=13±14
Find values of j: What are the two values of j? j = 13+14 implies j = 27. j = 13−14 implies j = −1. Values of j: 27, −1
