Question

What is the solution to the following equation?

x2 + 7x - 3 = 0

Answer 1

do you know the formula?

Answer 2

no

Answer 3

Good question !

Answer 4

\[ x=\frac{-b + \sqrt {b^2-4ac}}{2a}\quad\text{and}\quad x=\frac{-b - \sqrt {b^2-4ac}}{2a} \]

Answer 5

where Ax^2 + Bx + C = 0

Answer 6

\[\LARGE x_{1/2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}\]
\[\LARGE ax^2+bx+c=0\]

in your case you have:

\[\huge \underbrace{1}_{a}\cdot x^2\underbrace{+7}_{b}x \underbrace{-3}_{c}=0\]
