Question

give two examples of quadratic equations one which is quadratic equation and one which is not an quadratic equation​

Answer 1

•What are quadratic equations?

In algebra, a quadratic equation is any equation that can be rearranged in standard form as ax^{2}+bx+c=0 where x represents an unknown, and a, b, and c represent known numbers, where a ≠ 0. If a = 0, then the equation is linear, not quadratic, as there is no ax^2 term.

Example- x²−9=0 , y = x^2 + 3x + 1. y = x^2.

•What are non quadratic equations?

Since the product of the two factors is zero, one of the factors is zero. ... A non-monic quadratic equation is an equation of the form ax2 + bx + c = 0, where and are given numbers, and a ≠ 1 or 0.

Example- bx − 6 = 0 , x³ − x² − 5 = 0
