first the second term can be split up to make integrating it easierits easier if the x³ component is separatedthis eventually simplifies the second term to (-1/4) * x^-3so now the que...

An action potential travels towards the synaptic terminal down the axon in a wave depolarisation. The voltage gated calcium channels on the membrane of the presynaptic bulb open causing an influx of calci...

From Hitler and I, by Otto Strasser, published in 1940. Strasser was a leading member of the Nazi Party in its early years. Here he remembers a conversation with...

First, we need to factorise the denominator and therefore we use this formula: x_1,2 =[ -b + sqrt(b² -4 a c) ]/ (2a). You obtain two roots, x = 2 and x=3 and the integration is simpli...

x² - 8x + 12 = 0 (x - 4)² - 16 + 12 = 0 (x - 4)² - 4 = 0 (x - 4)² = 4 x - 4 = +- 2 x = 6 x = 2
