Use the quadratic formula to solve x² + 8x + 9 = 0. what are the solutions to the equation? round irrational solutions to the nearest tenth.
x=−1.2 and x=−6.8
x = 1 and x=−9
x=−6.6 and x=−1.4
x=−1 and x=−8

The solution set is x=-6.6 and x=-1.4

Option 3 is correct.

Step-by-step explanation:

Given:

Formula:

For given equation,

a=1 , b=8 and c=9

Substitute the value of a, b and c into quadratic formula.

Hence, The solution set is x=-6.6 and x=-1.4
