Question

Simplify the expression 5y^2+3y+5+3y^2-5-3y-8y^2

Answer 1

`\rm = {5y}^(2) + 3y + 5 + {3y}^(2) - 5 - 3y - {8y}^(2)`

`\rm = 5 {y}^(2) + {3y}^(2) - {8y}^(2) + 3y - 3y + 5 - 5`

`= 0`

Answer 2

The expression is
`5y^2+3y+5+3y^2-5-3y-8y^2`.

Collecting the constants, the first degree, and second degree terms together we have:


`(5-5)+(3y-3y)+(5y^2+3y^2-8y^2)=0+0+0=0`.

Answer: 0
