Also, factor this expression and simplify if necessary: (x+5)^2+6(x+5)(x-4)

Thanks.

I don't know what to do next, I think I'm supposed to get rid of the three, but I'm not sure how.

You can make a substitution to end up with a quadratic equation,

let u = square root of (x+6)

so you end up with

u

You can then solve for u and thn substitue back to solve for x.

For the second one, you may want to factor (x + 5) out.Nikola Tesla said:Also, factor this expression and simplify if necessary: (x+5)^2+6(x+5)(x-4)

(x + 5)

Can you go from here? :)
