We first identify the coefficient A equals one. Be equal six and C equal three. Next we just substitute A. B and C. With their values in this formula. So the denominator is to the numerator is minor six. So miners the square root of six squared minus four times one time in three ventricles minus six plus, minors the square road out 24/2 machine calls minus three plus some miners in the square without six. So if they use a calculator, the approximate value is miners 5.449 and the miners point 551
