In this tutorial, you'll see how to factor a quadratic equation using the guess and check method of factoring.Thus, in one single day Andrew covers part of the roof area, while Bill covers part of the roof area. Two tubes, working together, can fill the reservoir with the liquid in 12 hours.Working together, Andrew and Bill make of the whole work in each single day. The second root does not fit the given conditions: if Bill covers the roof in two days, then Andrew has 2-5=-3 days, which has no sense. The larger tube, if works separately, can fill the reservoir in 18 hours faster than the smaller tube. Find the number of girls present in the Sports Meet. In the Annual Sports Meet in a girls’ school, the girls present in the meet, when arranged in a solid square has 16 girls less in the front row, than when arranged in a hollow square 4 deep.Then, the speed of the boat up the stream (or against the stream) = (x - $$\frac$$) km/hour, and the speed of the boat down the stream (or along the stream) = (x $$\frac$$) km/hour.Therefore, time taken to travel 10 km up the stream = $$\frac$$ hours and time taken to travel 5 km down the stream = $$\frac$$ hours.i have tried them times and again, but nothing seems to work at all! The distributive property is a very deep math principle that helps make math work.In this lesson we present some typical word problems that may be solved using quadratic equations.Solution of quadratic equations is described in the lesson Introduction into Quadratic Equations in this module. Solution Let be the unknown current speed of the river in miles/hour.
