Question

find the zeroes of the polynomial function f(x)=4x^2-25​

Answer 1

Answer:

-5/2 and 5/2

Step-by-step explanation:

f(x) = 4x² - 25

to find the zeros of f(x)

then f(x) must be = 0

thus

4x² - 25 = 0

(2x)² - (5)² = 0

(2x - 5)(2x + 5) = 0

now

2x - 5 = 0 or 2x + 5 = 0

x = 5/2 or x = -5/2 ans
