To find the zeros of the function f(x) = x² – 25, we start by setting the function equal to zero:
f(x) = 0
x² – 25 = 0
Next, we can solve for x by adding 25 to both sides:
x² = 25
Now, we take the square root of both sides. Remember that taking the square root introduces both a positive and a negative solution:
x = ±√25
x = ±5
This gives us the zeros of the function: x = 5 and x = -5.
Now, to express the polynomial as a product of linear factors, we can use the zeros we found:
f(x) = (x – 5)(x + 5)
This factorization shows the polynomial x² – 25 as a product of its linear factors. Therefore, the complete answer is:
Zeros: x = 5, x = -5
Polynomial in linear factors: (x – 5)(x + 5)
