This is the easiest method of solving a quadratic equation as long as the binomial or trinomial is easily factorable. Otherwise, we will need other methods such as completing the square or using the quadratic formula. The following diagram illustrates the main approach to solving a quadratic equa...

Then a = 4, b = 5, and c = –6. Substitute these values into the quadratic formula: This gives two answers: or Note that the equation could have been solved by factoring: (4x – 3)(x + 2) = 0 Set each factor equal to zero: 4x – 3 = 0 or x + 2 = 0 ...
Use the quadratic formula to solve each of these equations. Express each solution in simplest form.
If you can memorise a certain formula you can write down the roots of a quadratic equation with hardly any effort of calculation. Although it looks hard, this formula is one of the two most memorable ones in mathematics. Since it has to apply to any quadratic equation we must represent ...
A quadratic equation is an equation that could be written as ax2+bx+c= 0 whena0. There are three basic methods for solving quadratic equations: factoring, using the quadratic formula, and completing the square. Factoring To solve a quadratic equation by factoring, ...
