Quadratic Equations

**Identification of quadratic equations**

**Example: **Check whether the following are quadratic equations or not.

(i) (2*x* + 3)^{2} = 12*x* + 3

(ii) *x* (*x* + 3) = (*x *+ 1) (*x* – 5)

**Solution:**

It is of the form *ax*^{2} + *bx* + *c *= 0, where *a* = 4, *b *= 0 and *c* = 6

Therefore, the given equation is a quadratic equa…
