Question

Check whether the following is quadratic equation or not.

3x2 - 5x + 9 = x2 - 7x + 3

Solution

Here it has been given that,

3x2 - 5x + 9 = x2 - 7x + 3

Now, after solving the above equation further we get,

2x2 + 2x + 6 = 0

x2 + x + 3 = 0

Now as we can see, the above equation clearly represents a quadratic equation of the form ax2 + bx + c = 0, where a = 1, b = 1 and c = 3.

Hence, the above equation is a quadratic equation.

  Is there an error in this question or solution?
