Linear equations and quadratic equations are two different types of algebraic equations. The degree of the equation is the factor that differentiates them from the rest of the algebraic equations.
A linear equation is an algebraic equation of degree 1. For example, 4x + 5 = 0 is a linear equation of one variable. x + y + 5z = 0 and 4x = 3w + 5y + 7z are linear equations of 3 and 4 variables respectively.
quadratic equation is an algebraic equation of the second degree. x2 + 3x + 2 = 0 is a single variable quadratic equation. x2 + y2 + 3x= 4 and 4x2 + y2 + 2z2 + x + y + z = 4 are examples of quadratic equations of 2 and 3 variables respectively.
