Question

Multiply:
(4 x² + 24 xy + 3 y²) by
(x² - xy + y²)​

Answer 1

Answer:

We have y−x=1 or y=1+x

Substitute y=1+x in the equation we get

x

+y

−xy=3

⇒x

+(1+x)  

2

−x(1+x)=3

⇒x

+x

+2x+1−x−x  

2

−3=0

⇒x  

2

+x−2=0

⇒(x−1)(x+2)=0

∴x=1,−2

When x=1⇒y=1+x=1+1=2

When x=−2⇒y=1+x=1−2=−1

∴{1,2} and {−2,−1} are the solutions of the above equations.
