just tell me what the imaginary roots are and how to put them in a factored equation such as when x=1 it is (x-1)

sorry forget the first equation i actually needed f(x) = x^3 + 6x -7

(x - 4) * (x + 1) * ( x + 2.5) = f(x)
If set to zero, your roots would be 4, -1, and -2.5

This cannot be factored. It can be solved using the quadratic equation and the perfect square method, but not by factoring

To factorize an problem, first take a look at its exponential value, and then use (most presumably) a guess and check method to configure your solution.

f(x)=2(x+1){(x-2)(x+1)-9.5}+3
