Firstly, increase the power outside the brackets by 1 and divide the whole thing by the new power. This gives 3/4(4x+1)4/3Next, divide the whole thing by the derivative of the bracket. The deri...
x2 -x -12 = 0. Here we have rearranged the equation so that we have 0 on one side of the equation, allowing us to now factorise. (x - ...
y = 2 (-1)2 -5(-1) -1y = 2 + 10 - 1y = 11y = 2 (2)2 -5(2) -1y = 8 - 10 -1y = -3
Step 1: Differentiate the equation Y = X^3 + X + 6 to find the gradient of the line at any point. To do this, multiply each term of X by the old power and -1 from that power. This makes dy/dx = 3X^2 + 1.S...
Rearrange both equations so that both are in the form y= something. Move the x terms to the right of both equations. y=5x+2 6y=30x+36 Factorise second equation so that common factor of 6 is shown...
