Look in an advanced maths book.
Improved answer:-
If the discriminant of the quadratic expression is less than zero then it's not possible to factor it.
Factorise it!
If it doesn't have an equal sign, then it's an expression, not an equation. The expression 7x2x is quadratic, because it equals 14x², and something is quadratic if it contains the squared exponent ².
Use the quadratic formula for the equality. Then, depending on the coefficient of x2 and the nature of the inequality [>, ≥, ≤, <], determine whether you need the open or closed intervals between the roots or beyond the roots.
Whether or not that there is a solution to a quadratic equation,
imaginary

The slope of your quadratic equation in general form or standard form.
The quadratic formula is famous mainly because it allows you to find the root of any quadratic polynomial, whether the roots are real or complex. The quadratic formula has widespread applications in different fields of math, as well as physics.
