A circuit with a cell of voltage 6V and two resistors of resistance 6 Ohms each connected in parallel. What is the current through the Cell?

Step 1 - draw the circuit.
Step 2- Finding total resistance of resistors in parallel, 1/Rt = 1/R1 + 1/R2 where Rt is the total resistance of the circuit.
Step 3- Use Ohms laws...

Show that (𝑥 − 1) is a factor of 𝑓(𝑥)=2𝑥^3 + 𝑥^2 − 8𝑥+ 5. Hence fully factorise 𝑓(𝑥) fully.

For the show that part of the question simply substitute all the 𝑥's in 𝑓(𝑥) with 1, as the factor 𝑥 − 1 means that 𝑥 - 1 = 0 therefore 𝑥 = 1. Once substituted in solve the equation and show that it is e...
