For example show that x + 3 is a factor of p(x) = x3 - 5x2 - 8x + 48
We need to show that when x = -3, p(x) = 0. If this is the case then x + 3 is a factor of p(x)

(This is something that I didnt fully understand for quite a while at school.) So when we are solving x2=25, in order to get x "on it's own" we square root both sides. However the def...
You will end up with an equation with the form y = mx + c you should be familiar with from GCSE First you would need to differentiate the equation of the line For example if you had f(x) = x3 +...
Curve: y = 3x2(x+2)6 Coordinate: (-1, 3)
This is typically a C3/4 level question because of the differentiation, but the rest of t...
Use substitution u=cos(x) resulting in du=-sin(x)dx: ∫0π/2sin(x)cos(x)^2dx = ∫0π/2-u^2du = [-1/3 u^3]x=0x=π/2 = [-1/3 cos(x)^3]0BSAnswered by Benedek S. • Maths tutor8891 Views
