(x-3) is the Factor of f(x) 4x^2-7x-15
Help me is this correct of finding the other factor?
If I may expand on acc100jt's solution a little:
If , then when we multiply out the RHS we get:
So, when we compare coefficients:
the coefficient ofand
the constant term:Check with the coefficient of :
, which is correctSo the other factor is
