= (4/3)x 3 - (10/2)x 2 + x 1/2 /(1/2) + C = (4/3)x 3 - 5x 2 + 2x 1/2 + C

Let's look at what makes this question more difficult than, say, 0.5 or 0.01: as the decimal is recurring, you can't just multiply and divide by a big number to get a fraction. Example: multiply 0.01 times 1...

The idea here is to pair your numbers up to get to the solution. If you were to put this through a calculator it would take you a while. However, if we simplify the problem to the sum of 1 to 10 you'll be ab...

Key points: Approach in exactly the same way as if there was an = instead of an <.When trying to solve the inequality, remember that whatever you do to one side of the inequality you must also do to the o...

You can solve this equation using the quadratic formula: x = -b +/- root(b 2 - 4ac) 2aSo, a=2, b=7, c=-8:x = -7 +/- root(7 2 - 4 x 2 x -8) 2 x 2So, x = 0.31 or -3.81
