Answer:
B
Step-by-step explanation:
First distribute the 2x to get:
4x² + 10x
Then distribute the -5 to get:
-10x - 25
Then combine
4x² + 10x - 10x - 25
The 10x's will cancel leaving you:
4x² - 25
Answer:
D
Step-by-step explanation:
That is impossible to answer because this is an expression. you can only solve for x in equations
