|4x+3|=9+2x  if we square both sides, we can eliminate the absolute values signs...

16x^2+24x+9=81+36x+4x^2  subtract the right side from both sides

12x^2-12x-72=0  now we can factor

12(x^2-x-6)=0

12(x^2+2x-3x-6)=0

12(x(x+2)-3(x+2)=0

12(x-3)(x+2)

So:

x= -2 or 3

Describe the end behavior of the function. f(x)=x^3+11x^2+35x+30
Lelechka [254]
To determine end behavior, we only have to look at the leading term.

First, the leading term is positive, so we won't have to negate anything.

The leading term has a power that is odd.

Since the exponent is odd, this means that the function goes to positive infinity as x goes to positive infinity.

This also means that the function goes to negative infinity as x goes to negative infinity.

Those are the end behaviors.

Have an awesome day! :)
