Answer 1

Answer:

For 4 ohm : Connect the 3 and 6 ohm resistors in parallel then connect 2 ohm resistor in series with them

For 1 ohm : Connect the 3 and 6 ohm resistors in parallel then connect 2 ohm resistor in parallel with both of them

Answer 2

Answer:

i don't know 2x^2-x+1 = 0,solve by factorisation methood

plz provide me product and sum factors or no.
