First multiply out the right hand side to get5x + 10 = 10x^2 + 20xThen rearrange so everything equals zero, forming a quadratic equation10x^2 + 15x - 10 = 0 To make things easier, you can simplify the equ...

A reflex arc is the nerve pathway which follows a reflex action. First a stimulus, like a pin prick, is detected by receptors in the skin. A sensory neurone then sends electrical impulses to a relay neuro...
