Question

solve the given equation by using quadratic formula X square + 5 x + 5 equal to zero​

Answer 1

Step by step explanation:

x² + 5x + 5 = 0

let a=1, b=5, c=5

x= -b +- root b² - 4ac/ 2a

= -5 +- root 25 - 20/2

= -5 +- root 5/ 2

= -5+- 2.236/2

x= -5+2.236/ 2 or x= -5-2.236/2

x= -1.382 or x= -3.618
