Question

la suma de las raices de la ecuacion : 10= 6x+x2 es :
4 --- 5/3 --------- 3/5 ---------- -6 -------- 6

Answer 1

Aplicando bascara
x^2+6x-10=0
a=1
b=6
c=-10
x1=(-b+raizcuad(b^2-4ac)/2a
x1=(-6+raizcuad(36-4(1)(-10))/(2(1))
x1=(-6+raizcuad(76))/2
x1=-3+raizcuad(19)

x2=(-b-raizcuad(b^2-4ac)/2a
x2=(-6-raizcuad(36-4(1)(-10))/(2(1))
x2=(-6-raizcuad(76))/2
x2=-3-raizcuad(19

x1+x2=-3+raizcuad(19)-3-raizcuad(19)
=-6
Rta. la suma de las raíces es -6
