First you input the equation into the quadratic formula: __________ x=<span><span><span>−<span>(<span>−2</span>)</span></span>±<span>√<span><span><span>(<span>−2</span>)</span>2</span>−<span><span>4<span>(1)</span></span><span>(5)</span></span></span></span></span> </span> ----------------------------- 2(1) Next you simplify the formula: ___ x=<span><span>2±<span>√<span>−16 </span></span></span></span> ------------ 2
35 minutes plus 30 minutes plus 20 minutes is 1 hour and 25 minutes. If you subtract this from 6:45, you get 5:25pm, which is your answer. Hope this helps!
you would have to make the equation 15+2x=43. After doing so you would have to subtract both sides do the equation to end up with 2x=28. The last step is to divide both sides of the equation by 2 to get x=14.
