Question

10x²+31x+3=0 usando bhaskara ?

Answer 1

10x² + 31x + 3 = 0 
Delta = b² - 4ac
a = 10
b = 31
c = 3 
Delta = (31)² - 4(10)(3)
Delta = 961 - 120
Delta = 841

X = (-b +- raiz delta) / 2a
X = (-31 +- 29) / 20
x' = (-31 + 29) / 20 = -2/20 = -1/10
x" = (-31 - 29) / 20 = -60 / 20 = -3

Answer 2

10x²+31x+3   Sendo a=10, b=31 e c=3 temos que:
x= -b+-√b²-4.a.c/2.a
x= -31+- √31²-4.10.3/2.10
x= -31 +- √961-120/20
x= -31 +- √841/20
x= -31 +- 29/20
x'= -31+29/20                   x"= -31-29/20
x'= -2/20                          x"= -60/20 
x'= -0,1                             x"= -3
