Why did you give the wrong one brainliest.
Q.7
If the absolute value is 2, what will be the number inside? Think on a number line. It should be either 2 or -2.
→ x-2=2 or x-2=-2 → x=4 or x=0
Q.8
Your teacher might have taught you that √x² = |x| but without reason. I'll tell you here. It is because the square root only considers positive solutions or zero.
"It is because the square root only considers positive solutions or zero."
Have you noticed something here? It is the definition of the absolute value!
We get |x|=-x+1. We must separate into two parts, where inside the absolute value is positive, 0 or negative.
1. x≥0 (Where |x|=x)
→ x=-x+1 → 2x=1 → x=1/2
2. x<0 (Where |x|=-x)
→ -x=-x+1 → 0=1 is falsehood. → No solutions exist.
