Solve for x in the equation x2+11x+121/4=125/4

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
 
 The solutions are:
 x1 = -11 / 2 - (5raiz (5)) / 2
 x2 = -11 / 2 + (5raiz (5)) / 2

The answer should be c.

If i think this is what your asking, he should look at the grams or pounds/ounces and compare the to their cost then max can identify which one is proportional and which is not ( i think xd)
