... square root. Ultimately, what the quadratic formula (y = -b +/- the square root of b^2 -4ac divided by 2a) tells one is the roots of the equation. The roots are the x-intercepts of the parabola a quadratic equation draws. For example, when solving the following quadratic equation, y = x^2 + 4x + 29, using the quadratic formula where a = 1, b = 4, and c = 29, one, comes out with the solution, -2 + 5i. This tells one ... that the parabola does not touch the x-axis, therefore does not have an x-intercept. The quadratic formula and the complex number system have a direct correlation. Unders...

... and because of his interests in geometry at the age of fourteen Pascal was admitted to meetings of French geometricians. At the age of sixteen he wrote an essay on conic sections and at age eighteen, he constructed the first arithmetical machine. When he was nineteen years old, Pascal began to create a machine that would be similar to an everyday calculator ... ...

... geometrics. That was when he began to discover things such asPascal's triangle,? which everyone who took high school mathematics, specifically geometry, should recognize. He wrote papers on his theories of conic sections, which are defined in Algebra two, used in a higher sense of mathematics and geometry as well. He even published discoveries on his thoughts of vaccums. Vaccums were a crazy man ... ...
