Which polynomial matches the expression -x(x – 5)?
x² – 5x
-x² + 5x
x² + 5x
-2x – 5
To find which polynomial matches the expression -x(x – 5), we need to expand it.
1. Distribute -x into (x – 5):
-x * x + (-x * -5)
= -x² + 5x
So, the expanded form of -x(x – 5) is -x² + 5x.
The correct answer is -x² + 5x.
