Multiplying a trinomial by a trinomial follows the same steps as multiplying a binomial by a trinomial. Determine the degree and
FinnZ [79.3K]

Answer: Degree of polynomial (highest degree) =4

Maximum possible terms =9

Number of terms in the product = 5

Step-by-step explanation:

A trinomial is a polynomial with 3 terms.

The given product of trinomial: (x^2 + x + 2)(x^2 - 2x + 3)

By using distributive property: a(b+c+d)= ab+ac+ad

(x^2 + x + 2)(x^2 - 2x + 3)=(x^2 + x + 2) x^2+(x^2 + x + 2) (-2x)+(x^2 + x + 2)(3)\\\\=x^2(x^2)+x(x^2)+2(x^2)+x^2 (-2x)+x (-2x)+2 (-2x)+x^2 (3)+x (3)+2 (3)\\\\\\=x^4+x^3+2x^2-2x^3-2x^2-4x+3x^2+3x+6

Maximum possible terms =9

Combine like terms

x^4+x^3-2x^3+3x^2-4x+3x+6\\\\=x^4-x^3+3x^2-x+6

Hence, \left(x^2\:+\:x\:+\:2\right)\left(x^2\:-\:2x\:+\:3\right)=x^4-x^3+3x^2-x+6

Degree of polynomial (highest degree) =4

Number of terms = 5

Arun is twice as old as Shreet 5 years ago his age was three times shree age find their present ages​
Mariulka [41]

Answer:  Arun is now 20, Shree is 10 years old

Step-by-step explanation:  

In the system of equations Arun's age is a. Shree is s

a = 2s .(current age equation)  Subtract 5 from each for five years ago,

a-5 = 3(s-5) . Substitute 2s for a in the second equation

2s -5 = 3(s-5)  distribute and reorganize

2s-5 = 3s -15 .   15 - 5 = 3s - 2s

10 = s .  Substitute into the first equation to find a

a = 2(10)

a = 20

5 years ago  Shree was 5 and Arun was 15
