Question

x square+2y by x cube -2xy+ y cube x=1 y=1 please give the answer step by step explanation please ​

Answer 1

Answer:

-2

Step-by-step explanation:

when we multiply x²+2y(x³-2xy+y³)=x to the power of 4-2x³y+x²y³+2x³y-4xy²+2y to the power of 4

then we Will get ,

X to the power of 4+x²y³-4xy²+2y to the power of 4

substitute 1 in the place of x and -1 in the place of y

so, we get,

1 to the power of 4+(1²)(-1³)-4(1)(-1)²+2(-1)to the power of 4

=1-1-4+2

=-2
