Just draw a graph and plot them on the graph then count how many squares (in short) there is between them.
I believe the sum of the root is: -3/2
And the product of the root is: 0
I hope this helps and have a great week :)
The answer is 25 degrees.
This is how you solve the equation, first you must know that the straight like ABC=180, DBC is 130, so the remaining amount is 50 degrees, BE is a bisector of ABD which means it splits ABD right down the middle. So ABE+EBD=50 degrees, 25+25=50 since both sides MUST be equal in order for BE to be a bisector of ABD.
