Answer:

see below

Step-by-step explanation:

whenever there is negative number being squared, you need to add the brackets so that you inside the - 1 in front of the number

so this step is wrong

\sqrt{ - 9 { }^{2} - 4(1)(20) }

the -9 ² , you must include the brackets to include the -1 in front of the 9

so it should be

\sqrt{( - 9) {}^{2}  - 4(1)(20) }

so you will get = 1

and then you continue with other parts of the formula and you will get real solutions

hope this helps
