Question

simplify x²y(x-5)+(x+y)(x²-1)-2y(x²-2x+1)
plz I want answer fast
minimum 5 steps plz...

Answer 1

x²y(x-5)+(x+y)(x²-1)-2y(x²-2x+1)

= x³y - 5x²y + x(x²-1)+ y(x²-1) - 2x²y +2xy -2y

= x³y - 5x²y + x³ -x + x²y-y - 2x²y+ 2xy - 2y

= x³y +x³- 5x²y - 2x²y + x²y + 2xy - x - 2y

= x³y + x³ - 6x²y + 2xy - x - 2y

= x( x²y+x² - 6xy + 2y -1 ) -2y

Answer 2

Hi,

x²y( x - 5 ) + ( x + y )( x²-1)-2y(x² -2x+1)

=x³ y - 5x²y+x³-x+x² y-y - 2x²y+4xy-2y

= x³y-5x²y + x²y - 2x²y + x³+4xy-x-y-2y

= x³y+(-5+1- 2 )x² y + x³+ 4xy -x+(-1-2)y

= x³ y - 6x²y + x³ + 4xy - x - 3y

I hope this helps you.
