Question

From the sum of 4+3x and 5-4x+2x2 subtract the sum of 3x2 – 5x and –x2 + 2x +5.​

Answer 1

Answer:

Step-by-step explanation: (4 + 3x )+ (5 - 4x + 2 x 2)

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

4 + 3x + 5 - 4x + 4

4 + 5 + 4 + 3x - 4x

13 - x

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

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

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

x2 - 3x + 5

(x2 - 3x + 5) - (13 - x)

x2 - 3x + 5 - 13 - x

x2 - x - 3x - 8
