The problem is bascially done to a point. (STEP 5) Then steps are missing. I give you steps 1 to 5, then I need you to solve for R1 and R2 in terms of RA and RB.
PLEASE Show all work including what I give you and show each step, each canceled term, or multiplication, or whatever.
STEP 1: R1 + R2 = RA
STEP2: R1 = RA - R2
STEP3: RB = (R1R2) / (R1 + R2)
STEP 4: RB = [(RA - R2)(R2)] / [(RA - R2)+(R2)]
STEP 5: RB = [(RAR2 - R2^2)] / [(RA-R2)+(R2)]
THEN MISSING STEPS....................................
R2 = RA(1 +/- [(SQRT1-4RARB)/2A] / 2
R2 = [RA +/- SQRT RA^2 - 4RARB] / 2© BrainMass Inc. brainmass.com September 27, 2022, 10:06 am ad1c9bdddf
The quadratic problems with variables missing steps are determined.
