Question

(–6s2 + 12s – 8) – (3s2 + 8s – 6) =

Answer 1

`{ \tt{( - 6 {s}^(2) + 12s - 8) - (3 {s}^(2) + 8s - 6) }} \\ = { \tt{ - 9 {s}^(2) + 4s - 2 }}`

Answer 2

4s - 2 - 9s²

Explanation:

(–6s2 + 12s – 8) – (3s2 + 8s – 6)

= -6s²+ 12s - 8 - 3s²- 8s + 6

= 12s - 8s - 8 + 6 - 6s² -3s²

= 4s - 2 - 9s²
