Consider the equation x^2+5x+6=0. In order to factorise this equation you first need to think of what numbers sum to make 5 (the coefficient of x) and whose product equals 6 (the number not multiplied by ...

First we need to get everything that is not x on to one side. This will then leave us with 4x=3g- 8s-9t. Now we need to remove the coefficient of x which will result in x=1/4(3g-8s-9t)- as we have x on it...

Two lines are parallel if they have the same gradient. The general equation for a straight line is y=mx+c, where m is the gradient and c is the y-intercept. If these lines are parallel, then m will be the...

First, you should make it so that each fraction has a common denominator. This will usually be done by multiplying the numerator and the denominator of the fraction by the same expression (this is accepta...

84/2 = 4242/2 = 2121/3 = 77 /7 = 1therefore answer is 2x2x3x7
