MCQ Questions for CBSE Class 10 Math Quadratic Equation Quadratic Equation And Its Solution With Answers

USe factorization.

Quadratic equation has 2 roots

Factorise the middle term.

Putting Values

 use of factorization of the middle term.

sum of roots =-b/a

product of roots = c/a

Factorise the middle term or use quadratic formula \\(x = {-b \\pm \\sqrt{b^2-4ac} \\over 2a}\\)

Pythagoras theorem

The standard form of a quadratic equation is \\(ax^2+bx+c=0\\)

Hint :

Start simplifying from below 

The equation that you will get after simplifying it i s

\\(x ^2 - 4x + 1 =0\\)

 \\(x ^2 - 4x +4 - 4+ 1 = 0 \\)

\\(x ^2 - 4x +4 = 3 \\)

\\({(x - 2)^2} = 3 \\)

\\(x - 2 = \\sqrt 3\\)
