Factorising x2-100: As there is no common element in x2 or 100, we know this must consist of two sets of brackets not just one. we know both brackets must contain and x, and that whi...
The question wants us to confirm the answer so the marks will be in the method unlike most questions which require you to find the answer. How to approach this is by thinking what ways can we calculate ar...
Location of two points that lie on the line is needed to define an equation of the line. The general equation of a line is in the form y = mx + c, where m is the gradient of the line and...
Insert 0 into the equation in place of Y as the Y co-ordinate is always 0 across the X-Axis.0 = 3x^0.5-x^1.5The x^0.5 can be factored out from the 3x^0.5 and the x^1.5 giving you...x^0.5(3-x^1) = 0 [As x^...
If side A is 3m and side B is 4m, what would be the length of the remaining side C?A = 3m ; B = 4m ; C =?Use Pythagoras Theorem to give the equation: A2 + B2 = C2 R...
