Answer:
20%?
Step-by-step explanation:
idk lol im pretty sure thats it
In completing the square, the first step is to factor out the first and second term so that the factor (x+a) is highlighted. This is seen in line 1. However, in line 2, the subtracted value should be 3 so as to compensate for the added value. This affects then line 3 as well. The answer is line 2.
This is super hard I tried like 20 times and it didn't work. Sorry
X= -2.8596 or rounded up -2.86 is the correct answer.
