Question

Check whether the following is quadratic equation or not.

x(x + 1) + 8 = (x + 2) (x - 2)

Solution

Here it has been given that,

x(x + 1) + 8 = (x + 2) (x − 2)

Now, solving the above equation further we get,

x2 + x + 8 = x2 - 4

x + 12 = 0

Now as we can see, the above equation clearly does not represent a quadratic equation of the form ax2 + bx + c = 0, because x + 12 = 0 is a linear equation which does not have a x2 term in it.

Hence, the above equation is not a quadratic equation.

  Is there an error in this question or solution?
