Find the zeros of the quadratic equation by factoring.

x^2-25=0

Answer 1

x=-5, 5

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.
`a^2-b^2 = (a-b)(a+b)`

`x^2 - 25 = (x+5)(x-5)`

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
