Therefore the coordinates of the turning point are (-1, 2). If we recall the general equation: \(y = a{x^2} + bx + c\) then if: a > 0, then the shape of the parabola is like a happy face and the ...

After all, people have been solving that equation for about 4,000 ... The only real problem is not many quadratic equations have A=1. For example, suppose you throw a ball straight up from 5 ...

c\). To get \(b\) (the number inside the bracket), halve the coefficient (number in front) of the second term in the original equation. Half of -6 is -3 so the bracket becomes \((x-3)\).

A mathematician and a computer scientist have just solved an "impossible" equation that has been considered unsolvable for ...
