i. Given that (x + 2) and (x + 3) are factors of 5x 3 + ax

Question:

i. Given that (x + 2) and (x + 3) are factors of 5x³ + ax² + b, find the values of the constants a and b.

ii. When a and b have these values, factorise 5x³ + ax² + b completely, and hence solve the equation 5^3y+1 + a x 5^{2 y} + b = 0, giving any answers correct to 3 significant figures.
