What are the zeros of f(x)= x squared - 10x +25

First factor the expression by using the perfect square rule and you'll end up with:

f(x) = (x - 5)^2

The roots or zeroes is the opposite of what is in the parenthesis, so it is 5

x = 5

Hope this helped! Mark as Brainliest Please! :)))

x^2 - 10x + 25 = 0

(x - 5)(x - 5) = 0

zeroes are x= 5 (multiplicity 2)

hi! i think the answer is 1/2 : )

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.
