In ancient times, algebra is used to find linear and quadratic equations.

al-Khwarizmi was a persian scientist.

The constant term in an expression or equation has a fixed value and does not contain variables.
So, $-7$ is the constant term in the expression, $4x^2+5x^6-7x^2-7+2x^2-7x^6$

Diophantus of Alexandria used algebraic equations and notations in presenting problems and solutions in Arithmetica.

Given polynomial is $x^3+2x^2-1+x^5-5x(x^2)$

A constant term is a value that do not have variable.
So, in this quadratic equation, −3−3 is a  constant term.

Clearly, the expression $4x^2-3x+7$  is a polynomial in one variable x because there is only one variable x in the expression having the highest power 2, which is whole number.

Clearly, the expression $y^2+\sqrt 2$  is a polynomial in one variable y because there is only one variable y in the expression having the highest power 2, which is whole number.

The expression $3\sqrt t+t\sqrt2$ contain the term $3\sqrt t$, here exponent of $t$ is $\dfrac12$, which is not a whole number.
Therefore, the given expression is not a polynomial in one variable.
