# A maths problem regarding zeroes of a polynomial?

i have a problem in maths
i m studying in class tenth
it was given in my NCERT book that
suppose we take
2x^2 - 8x + 6 = 2(x-1)(x-3)
then it was given that
x-1=0
x-3=0
so 1 and 3 are zeroes of the polynomials
my problem is that "how we can say that "x-3=0" and ...

then it was given that

x-1=0

x-3=0

so 1 and 3 are zeroes of the polynomials

my problem is that "how we can say that "x-3=0" and "x-1=0"

it was nowhere mentioned about dis???

plzz help urgently!

hey i saw jake's answer n i think its best

i could understand a bit

but then until u explained was ok

after that

either of the numbers (x-1, x-3) must be zero

i agree to that but in my book its been explained

that a quadratic polynomial has two zeroes n when it is made into a graph it forms a parabola

so i wanted to ask that how can we both of them i.e. x-1, x-3 as zeroes?????
