Answer» Since, it is given that -25 and+25 are the zeroes of the polynomial , therefore, f(x) = x3 – 6x2 + mx + n (x+25) and( x-25) are also the zeroes of the given polynomial. Now, consider the PRODUCT of zeroes as follows: (x+25) ( x-25) (x)^2- (25)^2 x^2-625 We now divide by f(x)= x3 – 6x2 + mx + n From the division, we observe that the quotient and the remainder |
