Question

Are the following two expressions the same?
`-(4t^2 -16t - 20)` AND
`4t^2 - 16t - 20`

Answer 1

No

Explanation:

Use - to open the bracket

`- (4t^2 -16t - 20) = \\ - 4 {t}^(2) + 16t + 20`

Compare the two

: They are not the same

`4t^2 - 16t - 20`

Note :

`- * - = + \\ + * - = - \\ + * + = + \\ - * + = -`
