The discriminant for a quadratic is the part of the quadratic formula that is under the square root.

$$x = {-b \pm \sqrt{b^2-4ac} \over 2a}$$

$$b^2-4ac$$ is the formula for discriminant.

$$11^2-4(1)(36)=-23$$

If the discriminant is negative, the quadratic will have 2 non real solitions. It it is positive, there will be 2 real solitutions. If it is 0 there will be 1 real solitution.

The discriminant is negative so your quadratic will have 2 non real solitutions.

Hi Guest!

$$1x+11x+36=0\\ 12x+36=0\\ 12x=-36\\ x=-36/12\\ \color{blue}x=-3$$

The discriminant indicates how many real solutions have an equation.

The discriminant is 1.

It does not have a discriminant - it is not a quadratic!   There is no squared term
