Find ∫(4x - 2/(x^3)) dx

Using the integer rule 1/ (xn) = x-n question becomes ∫(4x - 2(x-3)) dx

Then using the formula ∫xn dx = (xn+1)/n+1 and assuming there may be an integer value (+c) the answer is 2(x2) + x-2 + c

Yesterday it took 5 cleaners 4 and ½ hours to clean all the rooms in a hotel. There are only 3 cleaners to clean all the rooms in the hotel today. How much time will it take them?


Factorise and solve x^2 – 8x + 15 = 0


Simultaneous equation: (x-3y)=9,(2x+3y)=0


Solve x^2 - 3x - 10 = 0 for x by a) factorising and b) the quadratic equation. Then draw a graph of the function, marking when it touches each of the axes.
