In Product of Polynomial (x+11x+121) (x-11) =?

Sagot :

add like terms first
(12x+121)(x-11)
Multiply
12x²-132x+121x-1351
Add like terms again
12x²-11x-1351

Hope this helps =)
(x+11x+121)(x-11)

(x+11x+121)(x-11)
(12x+121)(x-11)

In this case, I'm going to use the FOIL method.

(12x+121)(x-11)
F: (12x)(x)
O: (12x)(-11)
I: 121x
L: (121)(-11)

Find the product.

F: (12x)(x) = 12[tex] x^{2} [/tex]
O: (12x)(-11) = -132x
I: 121 x
L: (121)(-11) = -1331

Combine and then add like terms.

12[tex] x^{2} [/tex] - 132x + 121x - 1331
12[tex] x^{2} [/tex] -11x -1331

So the answer is [tex]12 x^{2} -11x -1331[/tex]
