Question

the value of discrimination of equation x²+5x+5=0is​

Answer 1

Answer :

• the value of discrimination of equation x²+ 5x + 5 = 0 is 5

Given :

• x² + 5x + 5 = 0

To find :

• Discrimination

Solution :

》x² + 5x + 5

here,

• a = 1
• b = 5
• c = 5

Now we have to find the discrimination

As we know that,

• D = b² = 4ac

where , D is discrimination

》D = b² = 4ac

》D = (5)² - 4(1)(5)

》D = 25 - 20

》D = 5

Hence , The value of discrimination of equation x²+ 5x + 5 = 0 is 5

Answer 2

✫ The value of discriminant is 5 ✫

Step-by-step explanation:

As we know that,

• The nature of the roots of the quadratic equation ax² + bx + c = 0 and we know discriminant is Δ = b² - 4ac.

Given equation: x² + 5x+ 5 = 0

Here,

• a = 1
• b = 5
• c = 5

Putting the values,

• → Δ = b² - 4ac
• → Δ = (5)² - 4(1)(5)
• → Δ = 25 - 20
• → Δ = 5

If Δ > 0 then the roots are real and distinct, Where 5 > 0

• The roots are real and distinct.
• The discriminat is 5 .
