Question

Find the discriminant of the following equation x2+5x-6=0 (1) 1 (2)48 (3)-48 (4)49​

Answer 1

Answer:

${x}^{2} + 5x - 6 = 0 \\ \\ here \: a = 1 \\ \\ b = 5 \\ \\ c = - 6 \\ \\ discriminant \: formula \\ \\ {b}^{2} - 4ac \\ \\ = {(5)}^{2} - 4 \times 1 \times ( - 6) \\ \\ = 25 - ( - 24) \\ \\ = 25 + 24 \\ \\ = 49$

➡ option (4) = 49

Answer 2

$\huge\underline\mathfrak\color{purple}{Answer}$

Given equation : x²+5x-6=0

a = 1

b = 5

c = -6

Discriminant = b²- 4ac

=> (5)² - 4 (1) (-6)

=> 25 + 24

=> 49

Hence option 4 is correct.
