Question

Write the values of α+β and αβ if a = 3, b = 6, c = 9.​

Answer 1

Answer:

Hope this helps you

Step-by-step explanation:

Here,

a=3,b=6,c=9.

Then,

x=-b±√(b²-ac)/4ac

=-6±√(6²-3.9)/4.3.9

=-6±√(36-27)/108

=-6±(√9)/108

So,

α=-6+3/108

=-3/108

=-1/36

ß=-6-3/108

=-9/108

=-1/12.

Therefore,

α+ß=-1/36-1/12

=-1-3/36

=-4/36

=-9.

αß=-1/36.-1/12

=1/432.
