Simplify the expression.
x(5x-4)
A) 4x²-5x
B) -5x-4x
C) 5x+4x
D) -5x²+4x
D) -5x²+4x
To simplify the expression x(5x - 4), you need to multiply each term inside the parentheses by x.
The expression becomes:
x * 5x - x * 4
Simplifying further, you have:
5x² - 4x
Therefore, the simplified expression is:
5x² - 4x
So, the correct answer is A) 4x² - 5x.
