The general form of a polynomial is: x² + bx + c = 0. Substituting the roots,
3² + b(3) + c = 0
3b + c = -9 --> eqn 1
(5 + √5)² + (5 +√5)(b) + c = 0
(5+√5)b + c = -30-10√5 --> eqn 2
Solving both equations simultaneously by subtracting eqn 2 from eqn 1,
(-2 - √5)b = 21 + 10√5
b = -8 - √5
Using eqn 1,
3(-8 - √5) + c = -9
-24 - 3√5 + c = -9
c = -9 + 24 + 3√5
c = 15 + 3√5
Hence, the polynomial is: <em>f(x) = x² + (-8 - √5)x + (15 + 3√5)</em>.
4*m*3/3*m*2*n*x*9*n*2/30*m*2*n*2 evaluates to 96/5n^3m^3mx and that is the final answer.

√5 x (10 - 4√2)
Multiply the value outside the bracket by everything inside:
10√5 - 4√10
Thus, your answer is ten square root of five minus four square root of 10
