It was -7

@faketiffanypayne 

$\sf\Large (x-a)(x-a)=0$

then:

$\sf \Large x-a=0 $

$\sf\Large x=a$

@faketiffanypayne If you did what Pooja told you to do, that is the answer you would have arrived.

Also keep in mind that OpenStudy is not meant for giving you answers, we are here to teach you how to get to the answer.
