Answer:
( - 5 ± √ 23 )
Step-by-step explanation:
Given :
x² + 10 x + 2 = 0
We know :
x = ( - b ± ( √ ( b² - 4 a c ) ) / 2 a
Putting values here we get :
= > x = ( - 10 ± √ ( 10² - 4 × 1 × 2 ) ) / 2
= > x = ( - 10 ± √ ( 100 - 8 ) ) / 2
= > x = ( - 10 ± √ 92 ) / 2
= > x = ( - 5 ± √ 23 )
Therefore , value of x is ( - 5 ± √ 23 ) .
