ok

OpenStudy (kaydra14):

what is the question you need help with @AhhhhhplzzzzzHelp

OpenStudy (anonymous):

What is the solution set to the equation (x - 4)(x + 3)=0

OpenStudy (anonymous):

{3, -4} {-3, -4} {-3, 4} {3, 4}

OpenStudy (anonymous):

@KamiBug please help

OpenStudy (kaydra14):

(-3,4) that is your answer

OpenStudy (kaydra14):

@AhhhhhplzzzzzHelp

OpenStudy (kamibug):

Set each factor equal to zero and solve for x. x - 4 = 0 x = 4 x + 3 = 0 x = -3

OpenStudy (anonymous):

thanks guys can you help me with my other one's

OpenStudy (kaydra14):

sure

OpenStudy (kamibug):

Sure :)

OpenStudy (anonymous):

2. What is the solution set to the equation (2x 6)(3x 4)

OpenStudy (anonymous):

2x-6 3x-4

OpenStudy (anonymous):

=0

OpenStudy (kamibug):

Again, just set each factor equal to 0 and solve for x.

OpenStudy (anonymous):

Option A: -4/3,-3 Option B: 4/3,3 Option C: 4/3,3/4 Option D: {2}

OpenStudy (kaydra14):

option B

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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:)

OpenStudy (kamibug):

No problem :)
