rect Question :-

Find the value of b² - 4ac if a = 6 , b = 7 & C = 2

a) 1

b) - 1

c) 2

d) - 2

Solution :-

Given ,

a ( coefficient of x² ) = 6
b ( coefficient of x ) = 7
c ( constant term ) = 2

By SUBSTITUTING the values of a , b & c in the given question we can have the value of b² - 4ac

➸ b² - 4ac

➸ 7² - 4 ( 6 ) ( 2 )

➸ 49 - 24 ( 2 )

➸ 49 - 48

➸ b² - 4ac = 1

Hence , b² - 4ac = 1
