# What is the value of the discriminant for the quadratic equation –3 = –x^{2} + 2x?

Quadratic equations are those equations that have a degree equal to two. They can have at most two roots. Those roots can be found by using discriminants.

## Answer: The value of the discriminant for the quadratic equation –3 = –x^{2} + 2x is 16.

Let's understand the solution in detail.

**Explanation:**

The given equation –3 = –x^{2} + 2x can be written in the standard form as x^{2} - 2x - 3 = 0

Now the equation is of the form ax^{2} + bx + c.

The discriminant of the above general equation can be found by using the formula; D = b^{2} - 4ac.

Here, we have a = 1, b = -2 and c = -3.

Therefore, the discriminant of the above equation D = (-2)^{2} - 4(1)(-3) = 16
