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

How do I solve this problem
Ronch [10]

\overline{LK}\cong\overline{MK}\\LK=MK=7x-10\\KN=x+3\\MN=9x-11\\KJ=28\\\\MN=MK+KN\\\text{therefore we have the equation:}\\9x-11=(7x-10)+(x+3)\\9x-11=8x-7\ \ \ |+11\\9x=8x+4\ \ \ \ |-8x\\x=4

LJ=LK+KJ\\\\LK=7x-10\to LK=7(4)-10=28-10=18\\\\\text{therefore}\\LJ=18+28=46

Answer: LJ = 46.
