1.a. (3 marks)
 = 54a \sqrt{a} x {}^{3} + 27a {x}^{2} - 51 \sqrt{a} + 12)
where a is non-zero constant. show that a stretch scale factor 3√a parallel to the x-axis transforms the curve y=f(x) onto the curve y=g(x) where
 = 2 {x}^{3} + 3 {x}^{2} - 17x + 12)
1.b. (3 marks) hence find the solutions to f(x) =0, giving your answers in terms of a.
honestly algebra confuses me so much that i have no way to answer .
