1)2x^2 + 3x + 1 = 0
a=2,b=3,c=1
D=b^2-4ac
D=9-8=1
x(1,2)=-b+- корень из D/2a
x(1,2)=-3+-1/4
x1=-3+1/4=0,5
x2=-3-1/4=-1
2)3y^2 + 7y - 6 = 0
a=3,b=7,c=-6
D=b^2-4ac
D=49+72=121
y(1,2)=-b+- корень из D/2a
y(1,2)=-7+-11/6
y1=-7+11/6=2/3
y2=-7-11/6=16/6=8/3=2 целых 1/3
3)4z^2 - 11z - 3 = 0
a=4,b=-11,c=-3
D=b^2-4ac
D=121+48=169
z(1,2)=-b+- корень из D/2a
z(1,2)=11+-13/8
z1=11+13/8=3
z2=11-13/8=-1/4
