Answer
$x^2-22x+112=0$
Work Step by Step
Write the quadratic as the product of two linear factors and the leading coefficient: $a(x-r_1)(x-r_2)=0$, where $r_1$ and $r_2$ are the solutions.
$a(x-8)(x-14)=0~~$ (Make $a=1$ since it can be any real number except $0$)
$(x-8)(x-14)=0$
$x^2-14x-8x+112=0$
$x^2-22x+112=0$ (general form)
