Is this correct? distributive property

OpenStudy (quickstudent):

OpenStudy (anonymous):

looks good to me

OpenStudy (texaschic101):

distributive property is when you multiply everything in the parenthesis by the number outside of the parenthesis -5(4x - 3) = -5 * 4x + (-5) * -3 = -20x + 15

OpenStudy (quickstudent):

I'm a little confused because when I tried checking my answer on an algebra calculator, the answer they gave was -(20x - 15)

OpenStudy (quickstudent):

@texaschic101

OpenStudy (holly00d1248):

yep its correct

OpenStudy (quickstudent):

So, why did that calculator give that other answer? was it incorrect?

OpenStudy (quickstudent):

@texaschic101

OpenStudy (anonymous):

yes, it is correct. :)

OpenStudy (quickstudent):

So, was the calculator answer incorrect, or was it just written in another form?

OpenStudy (anonymous):

well, you see the negative sign on the outside. if you went on and distributed the negative (aka -1) to everything else, you would get your answer. :)

OpenStudy (quickstudent):

Oh, OK. Now I get it :)

OpenStudy (quickstudent):

Thanks!

no problem! :)
