This is why you studied completing the square in algebra. 49x^2+16y^2+160y=384 49x^2+16(y^2+10y+____)=384 + 16*____ 10/2 = 5 5^2 = 25 49x^2+16(y^2+10y+25) = 384 + 16*25 = 16*24 + 16*25 = 16*49 49x^2+16(y+5)^2 = 16*49 Okay, now you do one.
Thank you so much. Might have another question but have to run to class now. Thanks again...
