(-3,4) that is your answer

@AhhhhhplzzzzzHelp
OpenStudy (kamibug):
Set each factor equal to zero and solve for x.
x - 4 = 0
x = 4
x + 3 = 0
x = -3

Thanks guys so much I think I'm able to do the other one's now
OpenStudy (kaydra14):
your welcome
OpenStudy (anonymous):
how would I do it if it looked like this a2 - 25 = 0

would you add 25 to both sides
OpenStudy (kamibug):
You would add 25 to both sides, yes. :) Then you want to take the square root of both sides.
OpenStudy (anonymous):
so is this the correct solution set (0,5) or (-5,5)
OpenStudy (kamibug):
It would be -5 or 5, yeah. :)
OpenStudy (anonymous):
Thanks so muuuuuuuch:)
