Question

Solve each quadratic equation by using the factoring method. Match each equation with the corresponding solution.
-$x = - 7 , x = 9$ 
A) $x ^ { 2 } - 6 x - 40 = 0$ 
B) $x ^ { 2 } - 2 x - 63 = 0$ 
C) $x ^ { 2 } - 6 x - 7 = 0$

Quizplus · Accepted Answer

CB) Factoring $x^2 - 2x - 63 = 0$ gives $(x - 9)(x + 7) = 0$, which has solutions $x = 9$ and $x = -7$.C) $x^2 - 6x - 7 = 0$ does not match the solutions $x = -7, x = 9$, indicating an error in the selection. The correct match for the given solutions is only option B, as it directly factors into the roots provided. My previous explanation mistakenly included option C due to a misinterpretation of the solutions and the factoring process.
