Question

Q2. Find the value of discriminant (A) for the quadratic equation:
x2 +7x + 6 = 0. Hence tell the nature of the roots of the equation.​

Answer 1

Step-by-step explanation:

∆= b^2 -4ac

b =7

a= 1

c=6

b^2-4ac

=7(7)-4(1)(6)

=49-24

=25

which is a perfect square and more than zero

so the roots are rational and distinct

Answer 2

Answer:

A= 25 and real, different roots of the equation.

Step-by-step explanation:

x²+7x+6 = 0

Here, a= 1,b = 7 and c= 6

discriminant (A) = b²-4ac

= (7)²-4(6)(1)

= 49-24

= 25

since the discriminant (A) is a positive natural number that is not equal to zero.

so the roots will be real and different
