The variables a, b, and c represent polynomials where a = x2, b = 3x + 2, and c = x – 3. what is ab – c2 in simplest form?
3x3 + 2x2 – x + 3
3x3 + 2x2 – x – 3
3x3 + x2 – 6x + 9
3x3 + x2 + 6x – 9

The simplest form of will be and it can be determine by using arithmetic operations.

Given :

The following steps can be used to find the simplest form of :

Step 1 - Multiply A with B.

----- (1)

Step 2 - Now, Square the value of C.

Step 3 - Subtract from both the side of equation (1).

Therefore the correct option is D).
