Hi everyone. I was given a problem in which the roots of a quadratic function were given. Using those roots, I had to write the quadratic function, with integer coeffecients only. The roots were: (-1+ (sqrt -2))/5 and its conjugate. The equation I have so far is: f(x) = 5(x^2) + 2x + (3/5)...

Okay, I got it now - way easier than I originally thought it to be. Thanks for both of your responses. I really appreciate them. Have a great day!

Hi, I like Serena! Thanks for your response. Where would you substitute sin23x? Would you substitute it on the right hand side, so that: 1 - 2cos23x = 2sin23x Thanks again. (Sorry if this question seems a little silly.) - - - Updated - - - Hi, Euge. Ugh, that makes it so much easier...
