Answer:
x = -2, 2
Explanation:
this one is easy since we can just use squres to factor
(5x -10) (5x + 10)
we want one positive one and one negative one since there is no middle term.
so basically we finde the solution by setting each part of the binomial = to zero
like this
5x - 10 = 0
+ 10 +10
5x = 10
divide by 5 on both sides of the equal sign
x = 2
and
5x + 10 = 0
-10 -10
5x = -10
divide by 5 on both sides of the equal sign
x = -2
therefore the solutions (AKA the zeroes) are x= -2, 2
