Question

Find the value of discriminant

x²+7x-1=0​

Answer 1

Answer:

53

Step-by-step explanation:

Discriminant = b² - 4ac

= 7² -4×1×-1

= 49+4

= 53 Answer.....m

Answer 2

x²+7x-1=0

Here,

a=1, b=7, c=-1

Discriminant (∆) = b²-4ac

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= (7)²-4×1×(-1)

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= 49+4

⠀⠀⠀⠀⠀⠀⠀⠀⠀∆=53

$\therefore$∆=53
