Find the roots of the following equation 2x^2-11x+14=0

First start by copying down the question and making sure that you have copied all of the correct numbers. We then identify that it is a quadratic equation due to there being an x raised to a power 2 term. Due to this we can then use the quadratic equation. We then need to identify the a, b and c vaules. After identifying this we can calculate the discriminate of the equation to see if the roots do cross the x axis. The discriminate is 3 or 3/2 depending on the mentor of finding a b and c. We can then see that the equation crosses the x axis and thus we apply the quadratic formula and find that the roots are 2 and 3.5.
