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?

Vladimir [108]

AB = X^2(3X +2)

C^2 = (x - 3)^2

AB - C^2 = 3x^3 + 2x^2 - (x^2 - 6x + 9)

= 3x^3 + x^2 + 6x - 9

Morgarella [4.7K]

Answer:

I hope it helps u

Step-by-step explanation:

Let's solve your system by elimination.

15j+12k=18;5j+4k=6

Multiply the second equation by -3, then add the equations together.

(15j+12k=18)

−3(5j+4k=6)

Becomes:

15j+12k=18

−15j−12k=−18

Add these equations to eliminate j:

0=0

Answer:

Infinitely many solutions

Note: Please Brain-list it ok dear!
