Two trinomials are multiplied together. If the degree of the first trinomial is 4, what must the degree of the second trinomial be in order to have a product whose degree is 8?

The degree of the second trinomial must also be 4.

Step-by-step explanation:

The degree of the trinomial is the highest exponent on a variable. Also, if you multiply two x^4 together (you add the exponents when multiplying) you get x^8 which gives you that 8th degree you're looking for.

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
