Question

From the sum of 4 4 3 4 and 5 - 4x + 2x²,
Subtrust the sum of 3x²
32²-5r and
- x²+2x+5​

Answer 1

Step-by-step explanation:

(4+3x)+(5- 4x + 2x2) = 4 +3x +5-4x

+2x2

3x- 4x + 2x2+4 + 5

= -X +2x2 +9

(3x2-5x) + ((x2+ 2x +5) = 3x2-5x- x2

+2x+5

= 3x2-x2- 5x +2x + 5

2x2-3x +5

(x +2x2+ 9) - (2x2-3x +5)

-X+2x+9-2x2 + 3x - 5

-X+3x+ 2x2-2x2 +9-5

2x+4
