Firstly, we have to factorise the quadratic equation. So what this involves is finding two numbers which add up to 7 but also multiply to give 10 at the same time. To help you with this we can find common...

This question is best solved using conservation of energy, since it is stated that friction and drag (non-conservative forces) can be ignored.When the ball is released at the top of the slope, its initial...

Step 1: Rearrange equation to form x² + bx + c= 0  -Add 10 to both sides of equation: x²-7x +10=0 Step 2: Factorise the quadratic equation -Find tw...

Write 2x²+ 12x + 3 in the form p(x + q)²+ r Step 1: Factorise all the x terms using a common factor with brackets. In this case 2 is a common factor to both 2x²and 12x ===...

An action potential is generated within the axon of a neuron via a series of steps:1) the inside of the neuron at rest is negative (-70mV), called the resting potential2) Na ion channels open and inside o...
