Answer:

1.) 76

2.) 41

3.) 17

4.) -7

5.) 9

6.) 0

Solutions:

1.a=6 b=-2 c=-3

=(-2)²-4(6)(-3)

=4+72

=76

2.a=5 b=1 c=-2

=(1)²-4(5)(-2)

=1+40

=41

3.a=1 b= 5 c= 2

=(5)²-4(1)(2)

=25-8

=17

4. a=2 b=5 c=4

=(5)²-4(2)(4)

=25-32

=-7

5. a=2 b=-1 c= -1

=(-1)²-4(2)(-1)

=1+8

=9

6.a=1 b=4 c=4

=(4)²-4(1)(4)

=16-16

=0
