Question

4x²y+-3xy²+-5xy²+5x²y=​

Answer 1

4x²y + -3xy² + -5xy² + 5x²y

4x²y + (-3xy²) + (-5xy²) + 5x²y

4x²y - 3xy²- 5xy² + 5x²y

8x²y - 8xy² ( Taking out Common Terms.)

xy (9x - 3y)

Answer 2

4x²y+-3xy²+-5xy²+5x²y

Combining the like terms and adding

=4x²y+(-3xy²)+(-5xy²)+5x²y

=4x²y-3xy²-5xy²+5x²y

=4x²y+5x²y-3xy²-5xy²

=9x²y-8xy²
