Question

if a,b the root of xsqare +x+5=0 then asqare/b + bsqare/a​

Answer 1

Answer:

59/40

Step-by-step explanation:

a&b are roots of equation. so a+b= -1/2 , a×b=5.

so, a(sqr)/b + b(sqr)/a = {a(cube) + b(cube)} / a.b = (a3+b3)/5

now, (a+b)= -1/2, cubing it, a(cube)+b(cube) = 59/8

divide whole thing by a×b=5, answer= 59/40
