http://prntscr.com/8icv07 My answer is c, but it says choose all that applies, so im guessing there is more than one answer.

try puttin x=-5 in the options :) the one which becomes 0 on further simplification has -5 as a solution

OpenStudy (diana.xl):

would it be b?

imqwerty (imqwerty):

if u put x=-5 u get this - (x-2)^2 now putting x=-5 (-5-2)^2 (-7)^2 =49 so we are getting 49 and not 0 so -5 is not a solution of this equation

OpenStudy (diana.xl):

so it would be a

OpenStudy (diana.xl):

A and C are my answers yea?

imqwerty (imqwerty):

yes :)
