Question

find the discriminant of the equation x2-7x+2=0​

Answer 1

Answer:

x²-7x+2=0

a=1

b= -7

c= -2

D=b²-4ac

= (-7)²-4(1)(-2)

= 49+8

= 57

Discriminant - 57

Answer 2

Answer:

41

Explanation:

For a quadratic equation

ax^2+bx+c=0

discriminant is

(b^2-4ac)

Here b is -7, a is 1 and c is 2

Therefore discriminant is

(-7)^2-4*(1)*(2)

49-8

=41
