Explination: ok so to do this you will need to multiply so
-2.5 • 5
whats 2.5 • 5 it equals 12.5
and because the original number "-2.5" has a negative symbol you just go ahead and put that in there with it.
so your answer is -12.5
has the largest positive solution
Step-by-step explanation:
We can observe the given quadratic equations one by one.
We can see that the given quadratic equations are of the form
OR somehow simplify to the given form
The solution is:
x = ±c
So,
Option 1:
Option 2:
Option 3:
Option 4:
We can clearly see that:
has the largest positive solution

Answer:
the reciprocal is just x because x over 1 is just x
Step-by-step explanation:
Hope this helps! :)
Answer:
4x⁻¹
Step-by-step explanation:
4x + 20 25 - x²
_______ ÷ _______ ↷
x² - 5x [x - 5]²
4[x + 5] [-5 + x][5 + x]
_______ ÷ _______
x[x - 5] [x - 5][x - 5]
So what we did here was factor out ALL the Greatest Common Factors [GCFs] in each denominator and numerator, and since we are dividing vertically AND horizontally, according to this, ALL [x - 5] and [x + 5] cancel each other out and all you are left with is this:
4x⁻¹
OR
This, according to the Negative Exponential Rule [Reverse], is how you rewrite it as a fraction. You bring the denominator to the numerator while ALTERING THE INTEGER SYMBOL FROM POSITIVE TO NEGATIVE:
b⁻ⁿ = 1\bⁿ
I hope this helps you out alot, and as always, I am joyous to assist anyone at any time.
