00:02 CBSE solutions for Class 10 maths Quadratic Equations Q1. Check whether the following are quadratic equations :
(i) ( x + 1)^2= 2( x – 3) (ii) x^2– 2 x = (–2)(3 – x ) (iii) ( x – 2)(x + 1) = (x – 1)(x + 3) (iv) ( x – 3)(2 x +1) = x( x + 5) (v) (2 x – 1)(x – 3) = ( x + 5)(x – 1) (vi) x^2+ 3 x + 1 = ( x – 2)2 (vii) ( x + 2)3 = 2 x ( x^2– 1) (viii) x^3– 4 x^2– x + 1 = ( x – 2)^3
00:12 (ii)
00:22 Express quadratic equation in standard form.
01:08 Any equation of the form ax^2 + bx + c = 0, where p (x) is a polynomial of degree 2 and a is not equal to zero, is a quadratic equation.Obtain a,b and c values.
01:41 CBSE solutions for Class 10 maths Quadratic Equations Q1 (iii)
04:15 Here a=0.So, it not a quadratic equation.
04:20 (iv)
06:01 General form of quadratic equation
06:25 (v)
08:24 compare with general form of quadratic equation
09:19 (vi)
10:31 Here, Coefficient of x^2 is 0.So, given equation is not a quadratic equation.
11:25 (viii)
13:38 General form of quadratic equation
