Question

if x-a is the factor of the polynomial x3- mx2 -2xax + xa . than prove that a = m+x and a is not equal to 0

Answer 1

is (x-a) is a factor, that means, 'a' is a root of the polynomial.
So, f(a) = 0

So substitute 'a' in place of '0' in the equation of the polynomial, and equate it to zero.
Solving it, you'll get what you need to prove!

Answer 2

and how to prove that a = m+x

Answer 3

plz help

Answer 4

a = m + x?? this is senseless because 'x' is a variable, and 'm' and 'a' are constants, so, how can a constant be a sum of a constant and a variable?? Looks like a typo or a misprint.

Answer 5

no no u are incorrect x,m and a are variables
