x + 1 x = 1

A quadratic equation is any equation where x represents an unknown and also that can be rearranged in standard form as

a x 2 + b x + c = 0

.
When we simplify the given equation to form a quadratic equation, the result we get is

x 2 − x + 1 = 0

Here, the highest value of x is 2 which satisfy the rule of quadratic polynomial and therefore, it is a quadratic equation.
Hence, the correct option is 1.
