Answer:
x=-5, 5
Step-by-step explanation:
To factor an equation, break the polynomial into two binomials which multiply to make it. This is a difference of squares. Factor by taking the square root of each term. [tex]a^2-b^2 = (a-b)(a+b)[/tex]
[tex]x^2 - 25 = (x+5)(x-5)[/tex]
Once you have the factors, set them equal to 0 and solve for x to find the zeros.
(x+5)=0
x=-5
(x-5) = 0
x=5
