Question

Solve each quadratic equation by using the method of completing the square. Match each equation with the corresponding solution.
-$x = 1 , x = 7$ 
A) $x ^ { 2 } - 14 x = - 48$ 
B) $x ^ { 2 } - 20 x = - 99$ 
C) $x ^ { 2 } - 8 x = - 7$

Quizplus · Accepted Answer

Completing the square for equation C: $x^2 - 8x = -7$, we add 16 to both sides to get $(x-4)^2 = 9$. Solving gives $x = 1$ or $x = 7$.
