Answer:
1. 4x + 3
2. Binomial
Step-by-step explanation:
1. Given phrase,
Take 4x + 2 from 8x + 5
That is,
(8x+5) - (4x+2)
= 8x + 5 - 4x - 2
= 4x + 3 ( By combining the like terms )
Thus, OPTION B is correct.
2. An expression with one or more than one algebraic terms combined by addition or subtraction is called a polynomial.
There are different types of polynomial,
Monomial : Polynomial with one term,
Binomial : Polynomial with two terms,
Trinomial : Polynomial with three terms,
Four-term polynomial : Polynomial with four terms,
Five-term polynomial : Polynomial with five terms,
Here, the given expression,
[tex]a^2b - cd^3[/tex]
There are two terms [tex]a^2b[/tex] and [tex]cd^3[/tex].
Thus, it is a binomial.
