Question

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

Answer 1

Answer:

1+x

Step-by-step explanation:

4+3x+5-4x+2x²- (3x²-5x + -x²+2x + 5)

9-x+2x²- (2x²-3x+5)

9+x+2x²-2x²+3x-5

4+4x

1+x

Answer 2

Given :

⬤ From the Sum of 4 + 3x and 5x - 4x + 2x² .

⬤ Subtract the Sum of 3x² - 5x and -x² + 2x + 5 .

To Find :

⬤ Sum and Subtract of given expression.

Solution :

Sum of 4 + 3x and 5 - 4x + 2x² :-

4 + 3x + (5 - 4x + 2x²)

4 + 3x + 5 - 4x + 2x²

(4 + 5) + (3x - 4x) + 2x²

9 + (-x) + 2x²

9 - x + 2x²

2x² - x + 9 ----- (i)

Sum of 3x² and -x² + 2x + 5 :-

3x² - 5x + (-x² + 2x + 5)

3x² - 5x - x² + 2x + 5

(3x² + x²) + (-5x + 2x) + 5

2x² + (-3x) + 5

2x² - 3x + 5 ----- (ii)

Subtracting 2x² - x + 9 and 2x² - 3x + 5 :-

2x² - x + 9 - (2x² - 3x + 5)

2x² - x + 9 - 2x² + 3x - 5

(2x² - 2x²) + (-x + 3x) + (9 - 5)

0 + (2x) + (4)

0 + 2x + 4

2x + 4 $.$

Therefore , The Answer is 2x + 4 .
