Multiplying a trinomial by a trinomial follows the same steps as multiplying a binomial by a trinomial. Determine the degree and
Veseljchak [2.6K]

Degree = 4

Maximum possible number of terms for = 5

Solution:

Given expression:

\left(x^{2}+x+2\right)\left(x^{2}-2 x+3\right)

To multiply the trinomial by a trinomial:

\left(x^{2}+x+2\right)\left(x^{2}-2 x+3\right)

Multiply each of the first term by the each of the second term.

            =x^{2}(x^{2}-2 x+3)+x(x^{2}-2 x+3)+2(x^{2}-2 x+3)

            =(x^{4}-2 x^3+3x^2)+(x^{3}-2 x^2+3x)+(2x^{2}-4 x+6)

Remove the brackets and arrange the terms with same powers together.

            =x^{4}-2 x^3+x^{3}+3x^2-2 x^2+2x^{2}+3x-4 x+6

            =x^{4}- x^3+3x^2- x+6

The product of the trinomials is x^{4}- x^3+3x^2- x+6.

Degree is the highest power of the variable.

Degree = 4

Maximum possible number of terms for = 5

2x + 4y = 12 y = x – 3 What is the solution to the system of equations? (–1, 8) (8, –1) 5 1/2 1/2 5
Goryan [66]

Answer:

The solution is (8, -1).

Step-by-step explanation:

2x + 4y = 12..........(1)

y = 1/4x – 3 ..........(2)

Substitute y = x - 3 in equation (1):

2x + 4(1/4x - 3) = 12

2x + x - 12 = 12

3x = 24

x = 8.

Now substitute for x in equation (2):

y = 1/4 *8 - 3

y = -1.
