I'm supposed to factor this: 3z^2-17z+24 I used the quadratic equation, but I'm not sure if that's what I was supposed to use to get the answer. This is how I worked it... -(-17)+/-sqrt(-17^2-4(3)(24) --------------------------- 2(3) 17+/-sqrt(289-288) --...

another question I'd appreciate someone looking over is this one... (-7y-4)+(-9y^2+5y+7)-(-5y^2-7y-4) =14y^2+19y+7 is that right?

oh :( okay I definitely used the wrong method then. trial and error is a lot less steps than I used. thank you

george makes a $1000 down payment for a care and then pays $325 per month. Elaine makes a $2500 down payment for a car and then pays $325 per month. is there any number of month after which both george and elaine will have to paid the same amount
