Question

2y +y^2-xy -(xy_y+3y^2)

Answer 1

Whats the xy_y is that correct?

Answer 2

xy-y

Answer 3

\[2y+y^2-xy-(xy-y+3y^2)\]ok so the issue here is removing the brackets which means the signs change

Answer 4

2y+y^2 -xy-xy +y-3y^2

Answer 5

yes now collect terms as in -xy-xy = -2xy

Answer 6

2+1*y-y^2-xy-xy

Answer 7

\[-2y ^{2} + 3y - 2xy\]

Answer 8

The answer is \[-2y^2+3y-2xy\]

Answer 9

as NyteLyte has it

Answer 10

im sill working on it!!

Answer 11

\[2y+y^2-xy-xy+y-3y2\]collecting terms\[(2y+y)(+y^2-3y^2)-(xy-xy)\]so\[(3y)(-2y^2)(-2xy)\]finally rearrange so the largest coefficient is first and that gives the answer above

Answer 12

thanks Kevsturge and Nyte Lyte

Answer 13

okey.. gudluck..

Answer 14
