Add
(i) `5m(3-m) and 6m^2-13m-13m`
(ii) `4y(3y^2+5y-7) and 2(y^3-4y^2+5)`

Text Solution

Verified by Experts

`(i) 5m(3−m)and6m^2−13m−13m `
= `5m (3 - m) + 6 m^​2 - 13m-13m`
`=15m - 5m^2 + 6m​​^2 -26m`
`=m^2-11m`
`(ii)4y(3y^2+5y−7)and2(y^3−4y^2+5)`
`=4y(3y^2+5y−7)+2(y^3−4y^2+5)`
`=12y^3+20y^2-28y+2y^3-8y^2+10`
