first we identify the confessions of this equation. Eight equals four vehicles minus five and C equals eight. Next we substitute A B and C with their values into this form. The denominator is two times the numerator. Yes, five plus on minors. The square root of minus five squared minus four times four times a day, which he calls 45 plus a miner's the square root of minors, a hand bird and three over eight. Here we need to use I, which is the unit of the imaginary number, and I echoes the square root of minus one. So the first ones are rushing as five miners the square root of 100 spray I over ate. And the second solution is five plus square road out, handwritten and it's great. I over eight.
