Best ResponseYou've already chosen the best response.0what i need help with more than anything is understanding what i need to do in order. i suppose like a step by step list to understand how to find the zeros of a polynomial function

Best ResponseYou've already chosen the best response.0To do step by step, first set the polynomial equal to 0, then try factoring or use the quadratics..

Best ResponseYou've already chosen the best response.0The zeros of any function is the same as finding the xintercept. And, since ANY xintercept has a y value of 0, you set he entire function equal to zero in order to solve for x. That way, when you solve for x, you get ordered pair(s) of (x,0) etc (depending on the degree of your function. There are some exceptions to that rule, but for the most part it's the same. Does that help?

Best ResponseYou've already chosen the best response.0I undertstand now that i frist need to set the equation equal to 0. other than that do i just try to balance out the equation?

anonymous

Best ResponseYou've already chosen the best response.0or do all the x's in the equation turn to 0\

Best ResponseYou've already chosen the best response.0okay this is where i have gotten \[2x^39x+3=0\] i added 3 to both sides \[2x^39x=3\] i divided each side by 2 \[x^39x=1.5\] now what?

Best ResponseYou've already chosen the best response.0see I dunno if there was a 0 instead of 1.5 we could solve it... but even if u add a 1.5 to both sides ull end up with a 1.5 on the right..sorry i can't solve it..

Best ResponseYou've already chosen the best response.0Bahrom is right, it's unfactorable. That means you have no zeros. Which means there are no xintercepts. The graph is probably floating above or below the xaxis.

Best ResponseYou've already chosen the best response.0Btw, you can't divide both sides by 2. You can only do that if you factor out a 2 from both of the terms.
