How do I Multiply 3 polynomials.

Question

Can someone explain how to multiply more than two polynomials?  This is a problem I am having trouble with.

(x-2)(2x+3)(3-x)

 

Please help me understand how to do this. Thanks.

Answer 1

(x-2)(2x+3)(3-x) Take the first two and multiply as normal. Multiply everything in the first expression times everything in the second expression.

(2x^2 + 3x - 4x - 6)(3 - x) Combine like terms
(2x^2 - x - 6)(3 - x) Multiply everything in the first expression times everything in the second expression.

6x^2 - 3x - 18 - 2x^3 + x^2 + 6x Combine like terms.
-2x^3 + 7x^2 + 3x - 18

Answer 2

2x² + 4x - 5/4

Answer 3

13 5/8* 13 -1/8

Answer 4

(x-2)(2x+3)(3-x) - take the first 2 . To solve that Use FOIL Method

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

(2x²+3x-4x-6)(3-x) Combine like terms then multiply again.

(2x-x-6)(3-x)

2x^3 - x^3 - 6^3 -2x^x + x^x +6^x

6x-3x-18-2x²+x²+6x Combine again the like terms. 

-x²+9x-18 . 

 

Final Ans. : x²-9x+18
