Question

determine the roots and y-intercept of the following function using algebra.
g(x)=x^4−2x^3−7x^2+20x−12

Answer 1

what you have so far?

Answer 2

It looks like that will factor nicely, the roots are where the graph crosses the x-axis, or y=g(x)=0

Answer 3

Which way did you learn to factor , the synthetic division ?

Answer 4

have to go for a while sorry,
g(x) = (x-2)(x-2)(x-1)(x+3) = 0

those are the factors, gl
