Answer:
16
Step-by-step explanation:
We can calculate the value of x using Euclidean theorem
15^2 = 9 × (x+9)
225 = 81 + 9x subtract 81 from both sides
144 = 9x divide both sides by 9
16 = x
(x²+5)(x+2)
simple find the common factor between x³ and 2x² and the cf of 5x and 10
u will end up with these results then^
