Check whether the following equation is quadratic or not: (2x + 1)(3x + 2) =6(x – 1)(x – 2).
Quadratic equation is an equation with degree 2
By solving the given equation
(2x + 1)(3x + 2) = 6(x – 1)(x – 2)
we get,
6x 2 + 7x + 2 = 6x 2 – 18x + 12
25x – 10 = 0
The degree of the given equation is 1
∴ (2x + 1)(3x + 2) = 6(x – 1)(x – 2) is not a quadratic equation.
