Explanation:
The answer is D because to solve for X you use the quadratic formula which is...
-b±
![\sqrt{b^(2) - 4ac}](https://img.qammunity.org/2022/formulas/mathematics/high-school/gbl1nnemksev2j1708pgspp552jshluh0x.png)
now just plug in which would be
-6±
![\sqrt{6^(2) - 4(1)(4) }](https://img.qammunity.org/2022/formulas/mathematics/high-school/kbq2dd0aph0oz6j9sksi70p2jzv39udf3y.png)
then solve and the final answer would be
-6 ± 2
but there is only one answer for this which is a positive that is how I got
-6 + 2
