To solve this, you need to find two factors of -15 that total to give -2. The solution we're looking for is of the for (x + something) (x + something)=0, as you can then solve each bracket to get two resu...

From our base right angled triangle (base and height of 1) and remembering SOH CAH TOA ( tangent = opposite/adjacent), we can deduce tan(45) = 1 / 1 = 1

Find the highest common factor of each component. H.c.f. of 4 and 10 is 2, so:4x² + 10x = 2(2x² + 5x)H.c.f of x² and x is simply x, so:2( 2x² + 5x) = 2x(2x + 5...

First find the general solution to the differential equation y'' + 4y' + 3y = 0 as an arbitrary number of the solution to this differential equation can be added to the solution of the differential equati...

The Depression was an important reason why Hitler became Chancellor of Germany in 1933. First of all, the Depression had a negative economic impact on Germany. This meant the Nazis were able to increase t...
