    Answer:

    Hey friend

    here‘s your answer

    2x – x²+. 5 +(-4x -3 +7x²)

    2x-x²+5-4x-3+7x²

    2x-4x -x²+7x² +5-3

    -2x + 6x² +2

    Now,

    5-(-2x+6x²+2)

    5 +2x -6x² -2

    5-2+2x -6x²

    3 +2x – 6x²

    hope it helps you

    Step-by-step explanation:

    (2x -  {x}^{2}  + 5) + ( - 4x - 3 + 7 {x}^{2} ) is \: equal  \: to \:  \\  = 2x - 4x -  {x}^{2}  + 7 {x}^{2}  + 5 - 3 \\  =  - 2x + 6 {x}^{2}  + 2 \\  = 6 {x}^{2}   - 2x + 2 \\ now \: subtracting \: this \: from \: 5 \\ so  \:  \: \: 5 - (6 {x}^{2}  - 2x + 2) \\  = 5 - 6 {x}^{2}  + 2x  - 2 \\  = 6 {x}^{2}  + 2x - 2 + 5 \\ 6 {x}^{2}  + 2x + 3 \: is \: the \: answer....
