Question

Subtract the sum of 2x - x² + 5 and -4x - 3 + 7x² from 5​

Answer 1

Step-by-step explanation:

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

Answer 2

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
