Question

1. Which of the following expressions are polynomials in one variable and which are
not? State reasons for your answer.
2
(i) 4x^2 – 3x +7
(ii) y^2 + 2
(iii)
$3 \sqrt{t} + t \sqrt{2}$
​

Answer 1

Step-by-step explanation:

$1)4 ^{2} \: - 3x + 7is \: the \: polynomial \\ \\ 2)y ^{2} + 2 \: also \: polynomil \\ 3)this \: is \: not \: a \: polynomil \: because \: verialble \: never \: under \: the \: root \: \sqrt{t}$
