The other zeros of the polynomial if 3 is a zero is -4 and 1/2
If x = 3 is a zero of the polynomial function f(x) = 2x3 + x2 − 25x + 12, then x - 3 is a factor.
To get the other factor we will take the division of the polynomial and the factor to have:
2x^3 + x^2 − 25x + 12/x - 3 = 2x² + 7x - 4
Factorize 2x² + 7x - 4
2x² + 7x - 4 = 0
2x² + 8x - x- 4 = 0
2x(x+4)-1(x+4) = 0
(x+4)(2x-1) = 0
x = -4 and 1/2
Hence the other zeros of the polynomial if 3 is a zero is -4 and 1/2
