If we have a quadratic of the form it can be useful to put it in the form , as this will give us two equations that will give us both of the solutions of the quadratic, one is and the other is . So first if we are given the factored form of the […]
Read More Factoring QuadraticsAnother method of solving a quadratic is to complete the square. This changes the form of the quadratic from (1) Into the form (2) We can use the square of a binomial: (3) Using this we can see that for any equation of the form , in other words, where we can […]
Read More Completing the SquareA quick intro to quadratics! First a quadratic is any equation of the form where a,b & c are any real numbers, they produces a graph of the shape: Solving a quadratic, means we are finding the locations where the function equals zero, which is where the function crosses the y-axis, when . These locations […]
