Mathematical constants are built from the fabric of mathematics and can be determined a priori: Pi is based on the shape of a circle and can be calculated from numerous equations, e is from the growth ...
If a quadratic equation can be factorised, the factors can be used to find the roots of the equation. The equation factorises to give \((x + 3) (x - 2) = 0 \) so the solutions to the equation \(x^2 + ...
An alternative method to solve a quadratic equation is to complete the square. To solve an equation of the form \(x^2 + bx + c = 0\) consider the expression \(\left(x ...
