Step-by-step explanation:
Electronics comprises the physics, engineering, technology and applications that deal with the emission, flow and control of electrons in vacuum and matter.[1] It uses active devices to control electron flow by amplification and rectification, which distinguishes it from classical electrical engineering which uses passive effects such as resistance, capacitance and inductance to control current flow.

Answer:
- 2 a^2 - 2 c^2 + 2ad + 2cd - 4ac
Step-by-step explanation:
2c ( d - c - a )
= 2c ( d ) + 2c ( - c ) + 2c ( - a )
= 2cd - 2 c^2 - 2ac
2a ( d - a - c )
= 2a ( d ) + 2a ( - a ) + 2a ( - c )
= 2ad - 2 a^2 - 2ac
2c ( d - c - a ) + 2a ( d - a - c )
= 2cd - 2 c^2 - 2ac + 2ad - 2 a^2 - 2ac
= - 2 a^2 - 2 c^2 + 2ad + 2cd - 2ac - 2ac
= - 2 a^2 - 2 c^2 + 2ad + 2cd - 4ac
