Two approaches to the question are by either arguing in favour of yes or no. Either approach should contain at least one paragraph that supports the opposing view, but the strengths and weaknesses should ...

The factor theorem states that a polynomial f(x) has a factor (x-k) if and only if f(k)=0. 
f(2) = 3(2)^3 - 8(2)^2 + 3(2) + 2 = 3(8) - 8(4) + 6 + 2 = 24 - 32 + 8 = 0.
==> (x-2) is a fac...

Step 1 - Label y = x²  + 4x – 8 as equation 1 and y = - 2x – 17 as equation 2.Step 2 - In this particular question it is easier to eliminate the y variable from both equations, as they are both...
