Question

How should I do this?

Answer 1

Explanation:

`\sf \: (m)/(4) (6m - 8) + (m)/(2) (10m - 2)`

`\tiny {\sf (m)/(4) * 6m - (m)/(4 ) * 8 + (m)/(2) * 10m - (m)/(2) * 2}`

`\sf \: \frac{3 {m}^(2) }{2} - 2m + 5 {m}^(2) - m`

`\sf \: \frac{3 {m}^(2) + 10 {m}^(2) }{2} - 2m - m`

`\sf \: \frac{13 {m}^(2) }{2} - 3m`

This is the required answer
