Answer:
i have no idea what to do but you can go to khan academy and search up how to solve these kind of questions
Step-by-step explanation:
x^2-2x=x(x-2)
6x^2+12x=6x(x+2)
3x^3-9x=3x(x^2-3)
4x^2+28x^3=4x^2(1+7x)
9x = 3/5
x = 3/9*5
x = 3/45
x = 1/15
I think the answer is x-11x^5+12x
3 option is correct
because all the domains and ranges calculation matches in eqn 3
