Answer:
4x^2-25
Step-by-step explanation:
(2x+5)(2x-5)
Expand and remove the brackets. When this is done, you become less confused on what to do.
Remember brackets mean to multiply.
2x+5*2x-5
Solve the variables first.
2x*2x = 4x^2
5*-5= - 25
Answer--> 4x^2-25
Therefore 4x^2-25 is the correct answer ;)
Hope this helps!
