comment Calculate the value of a and b.
@azarel $7=-\frac{18-27b}{9}$ then $7=3b-2+6b$ but I didn't see 7 in this step in ur answer. thx

comment Calculate the value of a and b.
aww..i see, so sorry, $a+27b=18$ then $a=18-27b$

comment Find the gradient of the curve?
$\frac{-2x+8}{x^3}$ shouldn't be $\frac{-2x+8}{4x^3}$ or u cancel by $x$? thx alot.

comment Find the gradient of the curve?
why not derivative is $y=\frac{2}{2x}$ and how did it into $y'=\frac{2x^2-2x(2x-4)}{x^4}$ can u explain? thx

$-2=8a+b$ and $-5=16a-b$ but still can't get $a=-1$ and $b=4$ sorry about that!
