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

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 -

The value of b² - 4 a c = 100
