Question

Simplify this expression:2x2 – 5xy – 6 + 4x2 – 3xy + 1 - xyO 6x2 – 9xy-5O 5x2 - xy - 5 - y6x² – 8xy – 5-xyO 6x² +-2xy – 5 – x²y

Answer 1

The expression given is.

`2x^2-5xy-6+4x^2-3xy+1-x^2y`

Simplify the expression.

`(2x^2+4x^2)-(5xy+3xy)-x^2y-6+1`

Again simplify it more,

`6x^2-8xy-x^2y-5`

It can further written as,

Hence the correct option is C.
