Question

2) What is the value of the discriminant of a=6, b= -7and c=27​

Answer 1

Answer:

DiscriminantΔ=b

2

−4ac

Given:Discriminant =1

⇒b

2

−4ac=1 where a=6,b=b,c=2

⇒b

2

−4×6×2=1

⇒b

2

−48=1

⇒b

2

=1+48=49

∴b=±7

Answer 2

Step-by-step explanation:

discriminant =b^2-4ac

=(-7)^2-4×6×27

=49-648

= -599
