Question

Rewrite the expression by combining like terms 5X exponent 2 + 5Y plus 2X expontent 2 + 4Y exponent to subtracted by 4X exponent 2 + 2Y exponent 2 subtracted by 4Y

Answer 1

The given expression is,

`5x^2+5y+2x^2+4y^2-4x^2+2y^2-4y`

Combining the like terms, we get,

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