A quadratic equation is usually in the form:
where a, b and c are the coefficients of the expression and a ≠ 0.
If a = 0, the equation becomes a linear expression and is no longer quadratic.
Hence, in the above options; y = 5x -2 is the only one that is not a quadratic equation.
where a, b and c are the coefficients of the expression and a ≠ 0.

<h3>hello!</h3>
is the product of an irrational number and an irrational number always irrational?
We can easily check that by just multiplying some irrational numbers on our calculator.
Let's take
times
Multiply:-
The result is an irrational number.
Let's try to multiply π times itself.
Once again, we have an number.
Hence, the answer is:-
