Question

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

Answer 1

Answer:

x^2-2x-4

Step-by-step explanation:

The sum of :

4+3x and 5 - 4x + x^2

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

x^2-x+9

The sum of :

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

3x^2-5x-x^2+2x+5

2x^2-3x+5

Their subtraction:

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

2x^2-3x+5-x^2+x-9

ans:

x^2-2x-4
