Which one doesn't belong?

A: y = (x + 4)(x-6)
B: y = 2x^2 - 8x – 24
C: y = x^2 + 5x – 25
D: y = x^3 + 3x^2 – 10x – 24

And why?

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
