There are no soluions

2. tmrk

the solution is a complex no.

3. Test1

When you try the quadratic formula, you will have a negative number under the square root part: $\frac{-b \pm \sqrt{b^2-4ac}}{2a}=\frac{-2\pm\sqrt{4-36}}{2}=\frac{-2\pm\sqrt{-32}}{2}$ (This is equivalent to saying the discriminant is negative). As a result, there are no real solutions to this equation.

Solve x2 – 3x = 1

5. Test1

bring the 1 to the other side, and use the same procedure as above: $x^2-3x=1 \ \ \ \Longleftrightarrow \ \ \ x^2-3x-1=0$
