Timestamps: 00:12 Exercise 4.1 Q.1 Check whether the following are quadratic equations: (i) (x + 1)² = 2(x – 3) (ii) x² – 2x = (–2) (3 – x) (iii) (x – 2)(x + 1) = (x – 1)(x + 3) (iv) (x – 3)(2x +1) = x(x + 5) (v) (2x – 1)(x – 3) = (x + 5)(x – 1) (vi) x² + 3x + 1 = (x – 2)² (vii) (x + 2)³ = 2x (x² – 1) (viii) x³ – 4x² – x + 1 = (x – 2)³ Represent the following situations in the form of quadratic equations: 18:10 Exercise 4.1 Q.2 (i) The area of a rectangular plot is 528 m². The length of the plot (in metres) is one more than twice its breadth. We need to find the length and breadth of the plot.
