Question

grafica xfas y= 3x2 + 2x + 6

Answer 1

Respuesta:

y= 3x2 + 2x + 6

−3x2−2x+y−6=0  

(−3)⋅x2+(−2)⋅x+(y−6)=0

x=−(−2)±(−2)2−4⋅(−3)⋅(y−6)−−−−−−−−−−−−−−−−−−−−−−√2⋅(−3)

x=2±4−(−12y+72)−−−−−−−−−−−−−−√−6

x=−2±12y−68−−−−−−−√6

x=−2±(2)⋅3y−17−−−−−−√6

x=(2)⋅[(−1)±3y−17−−−−−−√](2)⋅(3)

x1=−1+3y−17−−−−−−√3

x2=−1−3y−17−−−−−−√3
