We have the following equation:
x2 + 11x + 121/4 = 125/4
Rewriting we have:
x2 + 11x + 121 / 4-125 / 4 = 0
x2 + 11x + (121-125) / 4 = 0
x2 + 11x + (- 4) / 4 = 0
x2 + 11x-1 = 0
Using resolvent we have the solutions are:
x1 = -11 / 2 - (5raiz (5)) / 2
x2 = -11 / 2 + (5raiz (5)) / 2
Answer:
The solutions are:
x1 = -11 / 2 - (5raiz (5)) / 2
x2 = -11 / 2 + (5raiz (5)) / 2
