Question

Hello, can someone plz help me answer question one?

Answer 1

`a^(2)+2a-3=0`

Add 3 to both sides, and you get:

`( a^(2)+2a -3) +3=0+3`

Next you want to identify the like terms an group them together.
You will get:

`a^(2) +2a + (-3+3)= 0 +3`

Now, you can combine (-3+3) together and you get 0
Now you have:

`a ^(2)+2a=3`

And, that's your answer. If you have any questions, just ask, and I hope this helps! :)
