Answer this question. explain how you got your answer

Option B)

Step-by-step explanation:

Given

To find

Option B) is correct

IF A = 3x² + 5x - 6 and B = -2x² - 6x + 7 then A - B equal is

The correct option is B

5x² + 11x - 13

Step-by-step explanation:

Given:

A = 3x² + 5x - 6     and

B = -2x² - 6x + 7

To Find :

(A - B) = ?

Solution:

A = 3x² + 5x - 6    

B = -2x² - 6x + 7

Now,

( A -B ) = (3x² + 5x - 6 ) - (-2x² - 6x + 7 )

Now first minus sign will enter in the bracket ,

( - )×( - ) = +

( - )×( + ) = -

∴ ( A -B ) = (3x² + 5x - 6 )  + 2x² + 6x - 7

              = 3x² + 2x² + 5x + 6x  - 6 - 7

               =  5x² + 11x - 13

∴ (A - B ) = 5x² + 11x - 13

Therefore,

IF A = 3x² + 5x - 6 and B = -2x² - 6x + 7 then A - B equal is

The correct option is B

(A - B ) = 5x² + 11x - 13
