First we identify the confession see as equals one vehicles minus three and C equals minus one. Next we substitute A B and C. With their values. Into this formula, the denominator is to the numerator is three plus miners, the square root of minus three squared minus four times one times minus one, which equals three plus miners square root of 13 over to. And if we use a calculator, their approximate values miners point 303 mm, 3.30 straight.
