Overview Of The Course: Quadratic equation is an important topic asked in exams. Usually5 questions are asked from this topic. If covered this topic with tricks, this topic will help you to score good marks in exams. What are Quadratic Equations? An equation with the form: ax2 + bx + c 0 is called a Quadratic Equation.

What Are The Different Tvpes of Equations 1.Linear Equation 2.Quadratic Equation What is Linear Equation? In a Linear Equation, the power or the degree of the variable(s) is 1 and it does not occur in any other powers. General Form: Ax By0 Ax + By = C Variable is the unknown value that needs to be determined. And constants are the values already given in the conditions in the question.

Linear equation with 1 variable: 4x-120 4x 12 x 12/4 3 x 3 Linear equations with 2 variables: 3x 2y 13 5x + 3y 21 y-2and x 3

Square and Square Root Case: X2 3600 and Y2 - 1600 X = +60 and-60 and Y +40 and-40 +60 is greater than +40 and -40 but -60 is less than both +40 and -40. Hence answer cannot be determined. X = 1600 and Y = V3600 X=+40 and-40 and Y = 60 Here 60 is greater than +40 and -40.

Cube Case: x3 1331 and y3-729 x 11 and y 9 x y =-1331 and -729 x =-11 and y = 9
