Question

what does a trinomial consist of ?

Answer 1

Examine the following expression which consists of one binomial in parentheses multiplying another binomial in parentheses.

(2k + 7)(3k - 10)

Using the FOIL Method, we can simplify the expression, obtaining the work below and a final result which is a trinomial.

6k2 - 20k + 21k - 70
6k2 + k - 70

After the two sets of parentheses were multiplied, like terms were combined. Notice that a trinomial, which consists of three terms, remains. This lesson explains how to factor a trinomial like this into two binomials (which we had before the FOIL Method was applied).

Answer 2

tri means three, so a trinomial has 3 terms

ex: x^2 + 2x + 1 is a trinomial since it has 3 terms

Answer 3

@jim_thompson5910 you had a way better answer. pick him

Answer 4

your answer is good too sarahjones667

Answer 5

essentially what sarahjones667 is saying is that if you FOIL out a binomial, you are likely to get a trinomial

Answer 6

Thanx .. once you have the trinomial how would your write it in ascending order @jim_thompson5910

Answer 7

you mean descending order right?

Answer 8

no the opposite ascending @jim_thompson5910

Answer 9

ok what you do is basically write the terms in order where the smallest exponent goes first

then you write the terms in order of the exponent

Answer 10

x^2 + 2x + 1 is in descending order

1 + 2x + x^2 is in ascending order

Answer 11

notice how the exponents are going up

Answer 12

oh yeah it makes sense now thanks
