Solve x^2-2x=24 by factoring.

x^2-2x=24
x^2-2x-24=0
(x-2)^2 (x+6)=0
x=2 or x=-6
[-6,2](answer)

5 answers

little mistake
x²-2x-24=(x-4)(x+6)
Factoring
x^2 - 2x - 24
=(x + 4)(x - 6)
Roots are -4 and 6.
I'm not sure what you mean by that.
I thought I had to put them in like ordered pairs.
I don't think it should matter. Perhaps your teacher might have some requirement. The answers are -4 and 6. These are both domain values for the function. When expressing domain and range values in a function, the x and y values are shown as (x,y) indicating (domain, range). So maybe you could express these as (-4,0) and (6,0). Maybe someone else can comment here about this.
