Kira solved the following radical equation using the steps shown to the right What mistake was made in Kira s work 8 2x x 4 8 2x x 4 2x 8x16 8 0 x 6x 8 0 x 4 x 2 x 4 and 2 A When Kira set the equation equal to zerio she should have gotten 2 10x 24 leading to the solution of x 12 and 2 B When Kira finished solving the radical equation she forgot to check for extraneous solutions which would leave x 4 as the only solution When Kira simplified 4 she should have simplified to get x 16 instead of 8x 16 D When Kira squared both sides to eliminate the radical she should have only squared the side with the radical and not both sides
