Q. Solve by completing the square.j2−16j−29=0Write 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 29 to both sides to set the equation up for completing the square. j2−16j−29+29=0+29j2−16j=29
Add 29: Choose the number to add to both sides to complete the square.Since (−216)2=64, add 64 to both sides.j2−16j+64=29+64j2−16j+64=93
Choose Number to Add: Factor the left side of the equation.j2−16j+64=93(j−8)2=93
Factor Left Side: Take the square root of both sides of the equation.(j−8)2=±93j−8=±93
Take Square Root: Solve for j by adding 8 to both sides of the equation.j−8+8=±93+8j=8±93
Solve for j: Calculate the approximate decimal values of j, rounded to the nearest hundredth.j≈8+93 or j≈8−93j≈8+9.64 or j≈8−9.64j≈17.64 or j≈−1.64
