«
»

This set of Mathematics Multiple Choice Questions & Answers (MCQs) focuses on “Polynomials in One Variable”.

1. (x-y)2 = __________
a) x2 + 2xy+y2
b) x2 – 2xy+y2
c) x2 – y2
d) x2 + y2
View Answer

Answer: b
Explanation: We can write (x-y)2 as (x-y) * (x-y) = x2-xy-yx + y2
= x2-2xy + y2.

2. How many terms are there in a polynomial 5x2+2x-2?
a) 1
b) 2
c) 3
d) 4
View Answer

Answer: c
Explanation: We can get number of terms by separating them by “+” or “” sign.
In the given polynomial 5x2+2x-2, if we separate expressions by “+” or “” sign, we get three separate terms as 5x2, 2x and 2.
Hence we can say that there are three terms in the polynomial 5x2+2x-2.

3. Which of the following is the example of Trinomial?
a) 9x3+ 5x2+7x+2
b) 9
c) 7x-2
d) 5x2+2x-2
View Answer

Answer: d
Explanation: Polynomials only having three terms are called Trinomials.
Hence to find trinomial polynomial, we have to find polynomial which has three terms. We can see that 5x2+2x-2 has three terms namely 5x2, 2x and 2. Hence it is trinomial.
Similarly, polynomials only having one term are called Monomials and polynomials only having two terms are called Binomials.
