Question

3. If A =3x² + 4x + 1 , B = 5x² − 3x + 8, C = 4x² − 7x − 3 , find the value of B + C – A.

Answer 1

Step-by-step explanation:

Given :

A = 3x² + 4x + 1

B = 5x² - 3x + 8

C = 4x² - 7x - 3

Find ; value of B+C - A

Solution ;

B + C - A

= (5x² - 3x + 8 ) + ( 4x² - 7x - 3 ) - ( 3x² + 4x + 1)

= 5x² + 4x² - 3x - 7x + 8 - 3 - ( 3x² + 4x + 1)

= 9x² - 10x + 5 - 3x² - 4x - 1

= 6x² - 14 x + 4 ( ans )....
