​

Answer 1

✒Question :

Find the discriminant of x²+5x+5=0 .

✒Answer :

${x}^{2} + 5x + 5 = 0$

a=1 ,b=5 ,c=5

$d = {b}^{2} - 4ac$

$= {5}^{2} - 4 \times 1 \times 5$

$= 25 - 20$

$= 5$

.: discriminant is 5 .

Answer 2

Answer:

GIVEN THAT

x²+5x+5=0

Comparing with ax²+bx+c=0 we get

a = 1, b = 5, c = 5

So the Discriminant

= b² - 4ac

= 5²-4×1 ×5

= 25 - 20

= 5
