Step-by-step explanation:
y = x² + x + 5
y = x + 1
x² + x + 5 = x + 1
x² + 4 = 0
x² = -4
x = ±√-4 undefined

Option → B
Given:
The expression is:

To find:
The factor of the given expression by GCF.
Solution:
We have,

Here, 3 is the greatest common factor (GCF) of
.
Taking out GCF, we get

Therefore, the required factor form of the given expression is
.
I think I might be wrong but try 25% (but like I said probably wrong)
80 / 100 = 1.25
100 - 80 = 20
So, 1.25 x 20 = 25%
