OpenStudy (shamim):

i think u know y=0 for x intercepts

OpenStudy (shamim):

then ur equation will b\[x ^{2}+x-12=0\]

OpenStudy (shamim):

or,\[x ^{2}+4x-3x-12=0\]

OpenStudy (shamim):

or,\[x(x+4)-3(x+4)=0\]

OpenStudy (shamim):

or,\[(x+4)(x-3)=0\]

OpenStudy (shamim):

x=-4

OpenStudy (shamim):

or, x=3

OpenStudy (amistre64):

it might help to let the asker participate somewhere along the way :)

OpenStudy (shamim):

ok @amistre64

OpenStudy (anonymous):

I think I understand it, thanks shamim but with these types of questions, do I have to put them into slope-intercept form?

OpenStudy (shamim):

wt is that

OpenStudy (anonymous):

y = mx + b

OpenStudy (shamim):

no

OpenStudy (shamim):

here u hv to put y=0 in ur equation

OpenStudy (anonymous):

ohh, ok. I understand it now, thanks!

OpenStudy (shamim):

u hv to put x=0 for y interception

OpenStudy (shamim):

u can give me a medal

OpenStudy (anonymous):

How would I do that? I'm still new here....

OpenStudy (shamim):

ok

OpenStudy (shamim):

just click best answer
