# X squared + 2x -35 how to solve this?

Mar 18, 2015

${x}^{2} + 2 x - 35 = \left(x + 7\right) \left(x - 5\right)$

It depends upon what you mean by "solve".
If you only need to factor the equation the answer is given above.

If you want to solve for $x$ if the given equation is set equal to $0$.
either
$\left(x + 7\right) = 0$
$\rightarrow x = - 7$
or
$\left(x - 5\right) = 0$
$\rightarrow x = 5$
