1st one u got the wron ans

OpenStudy (anonymous):

Can you help me

OpenStudy (anonymous):

OpenStudy (superdavesuper):

very very close on the 2nd one but still wrong :( the expression is right but one of the inequality is wrong.

OpenStudy (superdavesuper):

p^2-4p-32=(p+4)*(p___) fill in the blank there plz? :)

OpenStudy (superdavesuper):

wrong on the 3rd one too sorry :(

OpenStudy (anonymous):

I don't understand can you help me ?

OpenStudy (superdavesuper):

i will do the top on the 3rd eqn for u: \[z ^{2}*(z ^{2}+3z+2)=z ^{2}*(z+2)*(z+1)\] plz group the bottom half of the eqn

OpenStudy (anonymous):

HI :D

OpenStudy (superdavesuper):

for the first question, please group the top half like this: p^2-4p-32=(p+4)*(p___)

OpenStudy (anonymous):

p^2-4p-32= ( p+4)*(p-4) ?

OpenStudy (superdavesuper):

Please check ur math again because +4*(-4) is -16 and it should be -32

OpenStudy (anonymous):

p^2-4p-32= ( p + 4 ) * ( p - 8 )

OpenStudy (superdavesuper):

bingo...put that back in the eqn n the answer for 1st question should be....

OpenStudy (anonymous):

b ?

OpenStudy (superdavesuper):

that is correct :) for the second question, did u see what I said earlier? "very very close on the 2nd one but still wrong :( the expression is right but one of the inequality is wrong." so check the inequality plz

OpenStudy (anonymous):

would it be c

OpenStudy (superdavesuper):

correct again :) do u know what mistake u made there?

OpenStudy (anonymous):

yes i see what i did haha

OpenStudy (anonymous):

what about the third any idea?

OpenStudy (superdavesuper):

I did half of it for u already :P " i will do the top on the 3rd eqn for u: z2∗(z2+3z+2)=z2∗(z+2)∗(z+1) plz group the bottom half of the eqn"

OpenStudy (anonymous):

i don't know how haha sorry

OpenStudy (superdavesuper):

do u follow what I did w the expression above? the bottom one u can group them the same way....

OpenStudy (anonymous):

z+1*(z2+3z)

OpenStudy (superdavesuper):

(z+1)*z*(z+3) okay?

OpenStudy (anonymous):

okay i understand sorry

OpenStudy (superdavesuper):

put the top n bottom together, u will get....

OpenStudy (anonymous):

z2∗(z2+3z+2)=z2∗(z+2)∗(z+1) / (z+1)*z*(z+3)

OpenStudy (superdavesuper):

eliminating same express above n below....

OpenStudy (superdavesuper):

same expressions or terms
