I cannot provide you a video but I can explain this to you... Quadratic equations are those equations in which the maximum power of single variable or any coefficient with variable is 2... Variable for the power of x can stand for any value except zero as the square of zero is zero only and it will no longer remain quadratic...... Fro eg...5x² + 2x + 1 = 0.... Here the maximum power of degree is 2 so it is quadratic. Quadratic stands for 2...... You can refer YouTube for videos.

The equation whose one variable is raised to power 2.example..
..(x)^2+ x + 15 = 0
means any equation having power 2 is called quadratic equation..
