1) D = (-37) ^2-4*1*27=1369-108=1261

x1 = (- (-37) + 35,5) / 2*1=72,5/2

x1=36,25

x2 = (- (-37) - 35,5) / 2=1,5/2

x2=0,75

x1+x2=36,25+0,75=37

x2=36,25*0,75=27,19

2) x (x-210) = 0

x1=0

x2=210

x1+x2=0+210=210

x1*x2=0*210=0

3) y (1-y) = 0

y1=0

y2=1

y1+y2=0+1=1

y1*y2=0*1=0

4) D=41^2-4*1 * (-371) = 1681+1484=3165

x1 = (-41+56,26) / 2=15,26/2

x1=7,63

x2 = (-41-56,26) / 2=-97,26/2

x2=-48,63

x1+x2=7,63 + (-48,63) = - 41

x1*x2=7,63 * (-48,63) = - 371,05

5) y1=√19

y2=-√19

y1+y2=√19-√19=0

y1*y2=√19 * (-√19) = - √ (19) ^2=-19

6) x1=√ (10/3)

x2=-√ (10/3)

x1+x2=√ (10/3) + (-√ (10/3)) = 0

x1*x2=√ (10/3) * (-√ (10/3)) = - 10/3
