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
<em> The value of b² - 4 a c = ( 8)² - 4 (1)(-9) </em>
= 64 + 36
= 100
<u><em>Final answer:-</em></u>
The value of b² - 4 a c = 100
