Answer:
[tex]x^{2}[/tex] - x - 24 = 0
a = 1
b = 1
c = -24
Step-by-step explanation:
(x + 4)(x - 5) = 4
x(x - 5) = [tex]x^{2}[/tex] - 5x
4(x - 5) = 4x - 20
[tex]x^{2}[/tex] - 5x + 4x - 20 = 4
[tex]x^{2}[/tex] - x - 20 = 4
[tex]x^{2}[/tex] - x - 20 - 4 = 0
[tex]x^{2}[/tex] - x - 24 = 0
a = 1
b = 1
c = -24
