The company charges $ a0 per hour What is the value of b2 - 4ac for the following equation? x(x + 8) = 9

Mila [183]

Answer:

The value of b² - 4 a c = 100

Step-by-step explanation:

Given equation x(x + 8) = 9

⇒ x² + 8 x = 9

⇒ x² + 8 x - 9 =0

The standard form of quadratic equation

a x ² + b x + c

Here a = 1 , b = 8 , c = -9

The value of b² - 4 a c = ( 8)² - 4 (1)(-9)

= 64 + 36

= 100

Final answer:-

The value of b² - 4 a c = 100
