Question

Subtract these polynomials.

(4x2 – X+6) - (x2 + 3) =
O A. 482 - 2x+3
O B. 5x2 - x + 9
O c. 3x2 – X+3
O D. 4x2 - 2x + 9

dont say C just becuase its chosen, i didnt mean to

Answer 1

C

Explanation:

(4x^2-x+6)-(x^2+3)

First, you can change the second polynomial to make it an addition problem.

(4x^2-x+6)+(-x^2-3)

Then you add them together so 4x^2-x^2=3x^2

-x has nothing to subtract or add so we bring it down

and 6-3=3 making the answer

3x^2-x+3
