Question

Find the discriminant of the following equation:​

Answer 1

Answer:

x^2+5x-6=0

discriminant = 49

Answer 2

Given equation - x² +5x +6 = 0

Given equation - x² +5x +6 = 0Comparing it with ax² +bc + c = 0

Given equation - x² +5x +6 = 0Comparing it with ax² +bc + c = 0So

Given equation - x² +5x +6 = 0Comparing it with ax² +bc + c = 0So a = 1

Given equation - x² +5x +6 = 0Comparing it with ax² +bc + c = 0So a = 1b = 5

Given equation - x² +5x +6 = 0Comparing it with ax² +bc + c = 0So a = 1b = 5c = -6

Discriminate = b²-4ac

$= {(5)}^{2} - 4(1)( - 6) \\ = 25 + 24 \\ = 49$

Hence the discriminate is 49
