Question

Find the value of the discriminant of the equation x 2 + 10x - 7 = 0​

Answer 1

Answer :

• The value of discriminant is 128.

Given :

• x² + 10x - 7 = 0

To find :

• Value of the discriminant

Solution :

Given,

• x² + 10x - 7 = 0

We know that,

Comparing the equation ax² + bx + c = 0

Where,

• a = 1
• b = 10
• c = - 7

We know that formula of discriminant :

• D = b² - 4ac

Where,

• D is discriminant
• b is 10
• a is 1
• c is -7

Finding the value of discriminant :

↦ D = b² - 4ac

↦ D = (10)² - 4(1)(-7)

↦ D = 100 - 4(7)

↦ D = 100 + 28

↦ D = 128

Hence,

• The value of discriminant is 128.
