Question

Can anyone solve this for me? Ty:)​

Answer 1

so first of all you have to add

`3 {x}^(2) - 5x + 4 + 8x - 7 \\ 3 {x}^(2) + 3x - 3`

after getting the sum..you can add the answer( sum )to the given equation(5+3x-×^2)

`3 {x}^(2) + 3x - 3 + 5 + 3 {x} - {x}^(2) \\ {2x}^(2) + 6x + 2`

therefore your answer is

`2 {x}^(2) + 6x + 2`
