can u by any chance tell me the real solutions for 20x^2+17x-10=0
ok do u know the quadratic formula?
not anymore. lol i can plug in though if you canwrite it out
or u can just give me the answer:) lol
haha smart. well its better to know the formula for your future reference. :) |dw:1350961093023:dw|
