First we can identify the confessions of this. Aquarian ass A equals two vehicles, eight and C. Equals what next we substitute A B and C. With their values into the formula here, the denominator is two times two in the numerator areas minus eight plus some miners the square root of eight squared minus four times two times one, which is miners. Eight plant some miners the square root out 56 over four, which equals minus two plus some miners the square root of 14 over to and if they use a calculator, their approximate values minus three points 871 and my nurse point 129
