x^2y-5xy+6y+7x^2-35x+42
OpenStudy (anonymous):
solving for x?
OpenStudy (andriod09):
factoring
OpenStudy (anonymous):
xy(x-5)+6y+7x(x-5)+42=0
OpenStudy (anonymous):
(xy+7x)(x-5)+(6y+42)=0
x(y+7)(x-5)+6(y+7)=0
{x(x-5)+6}(y+7)=0....i am not sure tho

@andriod09 does that help?
OpenStudy (andriod09):
no, not really. but i have the answer.
OpenStudy (anonymous):

delta =1
x1=3 and x2=3
OpenStudy (anonymous):

that's it
OpenStudy (andriod09):
but its not the correct answer
OpenStudy (anonymous):
then do it other way
OpenStudy (andriod09):
the correct answer is:
(x-2)(x-3)(y+7)
OpenStudy (anonymous):
dude factor my last equation...you will get this

(x^2-5x+6)(y+7)=0
(x-2)(x-3)(y+7)=0
OpenStudy (andriod09):
no, your last equation as a quadratic equation, this is just a normal polynomial
OpenStudy (anonymous):
{x(x-5)+6}(y+7)=0
{x^2-5x+6}(y+7)=0
(x^2-3x-2x+6)(y+7)=0
(x-2)(x-3)(y+7)=0 @Nicole<3Algebra can you help further
OpenStudy (anonymous):
@andriod09 hope it is clear to you now?
