Question

Find the value of the discriminant of the equation x2+10x-7=0

Answer 1

Answer:

$\red{128}$

Step-by-step explanation:

Given equation:

x² + 10x - 7 = 0

Comparing the given equation with ax² + bx + c = 0, we obtain,

a = 1; b = 10; c = - 7

Discriminant (D) = b² - 4ac

Discriminant (D) = (10)² - 4(1)(-7)

Discriminant (D) = 100 + 28

Discriminant (D) = 128

∴ The value of discriminant is 128.
