Which of the following is the correct factored form of the given equation?

4x^2-25=0

a.(4x - 5)(x + 5) = 0
b.(2x - 5)(2x + 5) = 0
c.2(x - 5)^2= 0

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

hope i
