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:
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
