Question

9. Check whether the given equation is quadratic equation: (x +1)2= 2 (x-3)​

Answer 1

Answer:

∴ (x + 1)2 = 2(x – 3) is a quadratic equation. ∴ x2 – 2x = (–2) (3 – x) is a quadratic equation. ∴ (x – 2) (x + 1) = (x – 1) (x + 3) is not quadratic equation. ∴ (x – 3) (2x + 1) = x(x + 5) is a quadratic equation.
