Question

find the value of discriminat for each of the following equation √5x² -x- √5=0​

Answer 1

Answer:

-40.44

Step-by-step explanation:

5x²-7x+2√5=0

ANSWER:

D=b²-4ac

In equation

a=5

b= -7

c= 2√5

So

D= (-7)² - 4 × 5 × 2 √5kk km

= 49 - 40 √5

Hence we know that √5 = 2.236

So

49 - 40 × 2.236

49 - 89.44

Discriminant = -40.44

Answer is - 40.44
