Question

Determine which binomial is a factor of -2x^3+14x^2-24x+20
a.x+5
b.x+20
c.x-24
d.x-5

Answer 1

d) x - 5
you can easily verify it by equating 'x-5' to zero
i.e. x - 5 =0
=> x = 5
and now placing x = 5 in your original eqn in question. if you get zero as result, then 'x - 5' indeed is your solution.
