X =( -b +o- √b∧2-4ac)/2a
X=(-2+-√3∧2-4(2)(-152))/2(2)
X=(-2+-√9+1216)/4 X=(-2+-√1225)4
X1= (-2+35)/4...............................................................X1=33/4
X2=(-2-35)/4.................................................................X2=-37/4
Se aplica la fórmula general
a=2
b=3
c=-152
se sacan las dos solucione
x1=8,respuesta
x2=-9.5,respuesta
Espero te sirva
