Quadratic Equations : NCERT Class X
Chapter No 4 Quadratic Equations
Slide2 : The equation which is having two (2) as the highest power of the variable is considered as quadratic equation.
Quadratic equations always have two roots.
Slide3 : Here we will be discussing quadratic equations of one variable.
To solve the quadratic equations we know many factorization methods, viz.
Complete square method
Split-half method
etc.
Slide4 : In this current chapter we will be discussing about a unique method of solving a quadratic equation.
The new method we learn in this class is solving through
Sridharyacharya formula.
Slide5 : According to the Formula :-
Discriminant will decide the nature of the roots of the Equation; it is decided by the following three rules:- : Discriminant will decide the nature of the roots of the Equation; it is decided by the following three rules:- If D = 0, we have two equal roots of the equation.
If D > 0 then we have two unequal, real roots of the equation.
If D < 0 then we have two unequal, imaginary roots of the equation.
Slide5 : To solve the practical problems we need to translate the problem into equation and subsequently solve it.
