Question

x²+3/x=40
me ajudem,por favor​

Answer 1

Resposta:

x²+3/×-40=0

a=1, b=3 e c=-40

delta =b²‐4.a.c

delta =(3)²‐4.(1).(-40)

delta =9-4+40

delta =45

x¹=-b+_ raiz de delta/2a

x=-3+_raiz de 6/2a

x=-3-6/2.1

x=-9/2

x=-4,5

x²=-b²+_raiz de delta/2a

x²=-3+6/2a

x²=-3+6/2(1)

x²=3/2

x²=1,5
