2x + 24 = 9x - 39= 2x + 63 = 9x= 63 = 7x= x = 9
x = 20
(3x - 7)(2x + 9) = 0 x = 7/3 or -9/2
9 + 5x = -4x + 63 9 + 9x = 63 9x = 54 9x/9 = 54/9 x = 6
In reverse: 63 - 1 = 2n = 62 62 / 2 = 31 Now as the question: (2 x 31) + 1 = 62 + 1 = 63 Q.E.D.

x2+2x-63 = (x-7)(x+9) when factored
Simplifying x2 + -2x + -63 Reorder the terms: -63 + -2x + x2 Factor a trinomial. (-7 + -1x)(9 + -1x) Final result: (-7 + -1x)(9 + -1x)
