Question

On simplifying (-3y2 − 8) − (-5y2 + 1), we get

Answer 1

-3y2-8+5y2-1=

2y2-9

Explanation:

Answer 2

`\huge{\boxed{\sf{ 2y^(2) - 9 }}}`

Explanation:

`( - 3y^(2) - 8 ) - ( - 5y^(2)+ 1 )`

While subtracting , sign of each term of the second expression changes.

⇒
`- 3y^(2) - 8 + 5y^(2) - 1`

Combine like terms :
`-3y^(2)` and
`5y^(2)`

Like terms are those which have the same base.

⇒
`2y^(2) - 8 - 1`

Remember : The negative integers are always added but posses the negative ( - ) sign.

⇒
`2y^(2) - 9`

Hope I helped!
