Question

X^2-x+12 solve using the quadratic formula

Answer 1

The quadratic formula is $x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}$.

From the problem, a is 1, b is -1, and c is 12. Plugging in these values gives:

$x=\frac{-(-1(-1)\pm\sqrt{(-1)^2-4(1)(12)} }{2(1)}$

Because there is a square root of a negative number, there is no solution.
