Hey, when attempting these questions, do not cancel out anything
Here's a start for the first question:
Solve each term for 0.
Hello mastermin346You'll notice that you now have a factor of on both sides of the equation. So one solution is
(which you can solve for )
But if we can divide both sides by to get:
Now re-arrange this as a quadratic equation in , and solve.
If we put , the equation can be re-written:b)
Multiply both sides by , and re-arrange this as a quadratic. Solve for and hence .
Can you complete them both now?
