hay varios metodos formula general, completando cuadrados,etc
vamos con la formula general: x=( -b+-√b^2 - 4ac ) / 2a
3x²-5x+2=0
a=3, b=-5, c=2
x=(-(-5)+-√(-5)^2 - 4(3)(2) )/2(3)
x=(5+-√25-24)/6
x=(5+-√1)/6
x1=5+1/6=1
x2=5-1/6=2/3
4x²+3x-22=
a=4,b=3,c=-22
x=(-(3)+-√(3)^2 - 4(4)(-22) )/2(4)
x=(-3+-√361)/8
x1=-3+13/8=2
x2=-3-13/8=-2
x²+11x+24=0
a=1,b=11,c=24
x=(-(11)+-√(11)^2 - 4(1)(24) )/2(1)
x=-11+-√25/2
x1=-11+5/2=-3
x2=-11-5/2=-8
x²-16x+63=0
a=1,b=-16,c=63
x=(-(-16)+-√(-16)^2 - 4(1)(63) )/2(1)
x=16+-√4/2
x1=16+2/2=9
x2=16-2/2=7
9x²-12x+4=
a=9,b=-12,c=4
x=(-(-12)+-√(-12)^2 - 4(9)(4) )/2(9)
x=12+-√0/18
x1=12+0/18=2/3
x2=12-0/18=2/3
