Question :

x² + 3 = 2x³-1 is a quadratic equation.

(True or false)

Answer :

False, it is cubic equation.

Solution :

x² + 3 = 2x³-1

x² + 3 - 2x³ + 1 = 0

- 2x³ + x² + 4 = 0

As, the given equation isn't in form of :

ax² + bx + x = 0

Hence, it isn't a quadratic equation.

It is a cubic equation because it is in form of :

ax³ + bx² + cx + d = 0

Here, we don't have cx.

So, we can write it as 0x.

- 2x³ + x² + 0x + 4 = 0

In this equation,

  • a = - 2
  • b = 1
  • c = 0
  • d = 4
