Question

Qual a raiz: x²+x+vx²+x+10¬=10

Answer 1

 x²+x+vx²+x+10¬=10

x²+x+vx²+x+1 = 10 mmc = 10
                  10

10x² + 10x + 10vx² + 10x + 1 - 100 = 0

10x² + 10vx² + 20x - 99 = 0

(10 + v )x^2 + 20x - 99 = 0

delta = o
20^2 - 4.(10 + v).(-99)= 0
400 + 3960 + 396 v = 0
   396 v = - 4360
     v = - 4360 = - 2180 = - 1090
              396       198         99
