Question

From the sum of 4 + 3x and 5-4x + 2x²
Subrad the sum
of 3x²5x and x² + 2x+5​

Answer 1

Step-by-step explanation:

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

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

= 2x^2 -x + 9

Now find the sum of 3x^2 + 5x + x^2 + 2x + 5

= 4x^2 + 7x + 5

Now we subtract the first sum from second one

= 2x^2 - x + 9 - 4x^2 + 7x + 5

= -2x^2 + 8x - 6x
