We try the quadratic equation x2+ 21 = 10x. In order to use Proposition II-5, we rewrite this as 10x – x2= 21, or, factoring the left side, as (10 – x)x = 21. Comparing this to our formula above, we note that b = 10 and therefore we have 如此让我们看见如何使用这个等式...
4. Calculate the X-intercepts You can solve it using the quadratic formula: x = -b ±√(b² – 4ac) / (2a). Substitute the values of a, b and c into the formula. x = -(-4) ±√((-4)² – 4(2)(1)) / 2(2) x = 4 ±√(16 – 8) / 4 x = 4 ±√8 / ...

I got these solutions by solving the quadratic's factors. That's working frontwards. To get the quadratic from the zeroes, I just work the above process in reverse; that is, I work backwards. Finding the zeroes from the quadratic and finding the quadratic from the zeroes are just two ...
The vertex of a parabola is a point at which the parabola makes its sharpest turn. The vertex of f(x) = ax^2 + bx + c is given by (-b/2a, f(-b/2a)). Learn how to find vertex of a parabola from different forms like standard form, vertex form, and inter
