quadratic equation is an equation of second degree that use an initially sign in stand of equal sign the solution of quadratic inquality always give the two root
Answer:
It's inequality where you have the unknown with exponent 2 and no higher exponents.
For example:
[tex]x^2-5x+3<0\\\\4x>5x^2+1\\\\4x^2-1\geqslant0\\\\5\leqslant-10x^2[/tex]
These are NOT quadratic inequalities:
[tex]x^3-5x+3<0\\\\4x^2>5x^5+1\\\\4x^2-x^6\geqslant0\\\\5\leqslant-10x[/tex]
