Mark me as brainliest if this helps!
Both are not equivlant to the top speed of the model plane because caculator op.
This is known as quadratic algebra.
To find it, you can use the quadratic formula but that might take a while.
We can factor it out and get
-3(mx² + mx - 1)
We can then set mx² + mx = 1
It would have no solutions
Edit: Above is wrong! I made the mistake of factoring 3 when it cant be factored.
Here is the solution
mx²-3mx=-3
Divide both by -3
mx²+mx=1
And I really messed this up. Its been a long time since quad. Sorry, but I cant seem to get the answer. Try and look up the quadratic formula and see if you can use that
55,890
31% of 81,000 is 25,110
81,000 - 25,110 = 55,890
