# Math questions?

I have 2 problems...

1) how would you solve this?:

√(x+14) = x- 16

This is related to quadratics (particularly, i want the x intercepts)

2) How do you factor something that may be uncommon, easily..? for example:

x^2 - 9x + 25

1. Square both sides, expand, simplify to get a quadratic, complete square if necessary.

2. This can be a matter of advanced mathematics, but usually when something unusual cannot be factored, we say it is unfactorable. However, if it is present in an equation, it can be possible to solve for x.
