 Question 290815: the instructions state: Solve the Quatractic equation by factoring and using the Zero-Product Property. the problem is: 3y^2-11y=10 here is what i've done so far: i subtracted 10 from the right side so it will equal 0 then i added it to the binomial on the left. i got 3y^2-11y+10=0 next, i would have to factor the trinomial. i got this far: (3y^2-y)(-10y+10) this is where i got stuck because i cant factor it correctly in order to use the Zero-Product Property.

 Question 291300: I have never had such a problem with maths before. Everyone says it's easy, and it might be easy, IF I ONLY GOT THE HANG OF IT. I've alwayas got around math problems before, but this time,it's quadric equations, and it seems impossible. I read my textbook over and over again, but just don't get it. It's like, my mind is blocked. My teachers keep saying the same old things again, and again, and I just don't understand it. I'd be delighted to get some help from here, because I don't want to ruin my straight-'A's on my report card with an ass shaped B, or worse, "C". I don't know what to do, or where to start from. I'm flunking. Please help!!!! Aalia Click here to see answer by checkley77(12569)
