Subtract the sum of 2x-x2+5 and -4x-3+7x2 from 5

1.	Subtract the sum of 2x-x2+5 and -4x-3+7x2 from 5
Answer» As given in the question, the Sum of 2x – x² + 5 and -4x – 3 + 7x² is given as: = 2x – x² + 5 – 4x – 3 + 7x² = 2x – 4x – x² + 7x² + 5 – 3 = - 2x + 6x² + 2 (i) Now subtracting equation (i) from 5 we get, Subtracting (ii) from (i), we get = 5 - (-2x + 6x² + 2) = 5 + 2x – 6x² – 2 = 3 + 2x – 6x² Therefore, the resultant expression is 3 + 2x – 6x²

Answer»

As given in the question, the Sum of 2x – x² + 5 and -4x – 3 + 7x² is given as:

= 2x – x² + 5 – 4x – 3 + 7x²

= 2x – 4x – x² + 7x² + 5 – 3

= - 2x + 6x² + 2 (i)

Now subtracting equation (i) from 5 we get,

Subtracting (ii) from (i), we get

= 5 - (-2x + 6x² + 2)

= 5 + 2x – 6x² – 2

= 3 + 2x – 6x²

Therefore, the resultant expression is 3 + 2x – 6x²
