Question

find the dicriminant of the following education X2+5-6=0
​

Answer 1

Answer:

Step-by-step explanation:

equation = x² + 5x - 6

ideal form of quadratic equation = ax² + bx + c

comparing both equations , we get a = 1 , b=5 , c= -6

Discriminant = b² - 4ac

D= 5² - 4×1×(-6) = 25 + 24 = 49

Answer 2

Step-by-step explanation:

Solution :

x²+5x+6

By, Comparing the Equation with

ax² + bx + c = 0

We will get,

a = 1

b = 5

c = 6

D=b²-4ac

→D=(5)²- 4×1×6

→D=25-24

→D=1

Therefore,  D=1

Therefore, discriminant of the following equation is 1.
