Question

1. Which of the following expressions are polynomials in one variable and whic
not? State reasons for your answer.
(1) 4x2 – 3x +7 (i) y2 + 2
2
(ii) 3V1 + tv2
(iv) y +
(v) x10 + y2 + $50​

Answer 1

Explanation:

the expressions are polynomials in one variable

4x2 -3x+7

Answer 2

The equation 4x²–3x+7 can be written as 4x²–3x1+7x0

Since x is the only variable in the given equation and the powers of x (i.e., 2, 1 and 0) are whole numbers, we can say that the expression 4x²–3x+7 is a polynomial in one variable.
