x^2 = 4(x – 3)^2
This is a quadratic equation, which contains terms up to x2. All quadratic equations can be written in the form ax2 + bx + c = 0 where a, b
If s=ut + 1/2 at^2 , a) make a the subject of the expression b) make u the subject of the expression c) if s=10, t=2 and u=4 find the value of a
a) s=ut + 1/2 at2Firstly , take the ut to the left hand side of the equation in order to isolate the 1/2 at2.s-ut=1/2 at2 Then multiply both sides by 2 to leave just at
