first take the 6 to the other side. 31 = x2 + 10Then take the 10 to the other side by taking it away from 3121= x2square root 21 inorder to find xx= 4.58
When differentiating with respect to x, we multiply the coefficient of the 'x' by the power of the 'x', and subtract one from the power of 'x'. For example:y = 5x^5dy/dx = (55)x^(5-1) = 25x^4If the po...
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...
