Katie performed the steps shown below to solve a quadratic equation using the method of completing the square. X^2 - 12 = 2 -4x + 7y = 12 A, multiply each term x - 12y = 2 by -4 and add it to the other equation B, Add the corresponding sides of equation. C, multiply each term x - 12y = 2 by 4 and add it to the other original equation. C, isolate the x variable in the first equation
