    R2^2 -RAR2 + RBRA = 0

    NOW THE QUADRATIC EQ IS - b +/- SQRT B^2 - 4AC / 2A
    ------------------------------------------------------------------------------------

    THE PROBLEM STARTED OFF R1 + R2 = RA AND R1 = RA -R2, THEN RB = R1R2/R1+R2. EVERYTHING WAS SOLVED FOR RB UNTIL THE ABOVE ANSWER OF
    R2^2 -RAR2 + RBRA = 0.

    THE PROBLEM ASKS TO SOLVE FOR RA AND RB IN TERMS OF R1 AND R2:

    THE PERSON WHO DID THIS GAVE R2 = RA+/- SQRT RA^2 - 4RARB/2)

    AND R1 = RA-R2 = [RA +/- SQRT(RA^2-4RARB)]/2

    I HAVE NO CLUE HOW THEY GOT FROM THE QUADRATIC EQ OF R2^2 -RAR2 + RBRA = 0 TO THE ANSWERS OF R1 AND R2. PLEASE DO EVERY LITTLE STEP, EXPLAIN WHAT YOUR DOING TO GET THE FINAL ANSWER.

    quadratic problem

    I just posted a probelm, but did not get everyything I needed.

    OK, left off at:

    R2^2 -RAR2 + RBRA = 0

    NOW THE QUADRATIC EQ IS - b +/- SQRT B^2 - 4AC / 2A
    ------------------------------------------------------------------------------------

    ok, THE PROBLEM STARTED OFF R1 + R2 = RA AND R1 = RA -R2, THEN RB = R1R2/R1+R2. EVERYTHING WAS ...
