Negative and a positive makes a negative.
So, -25 + 25 = 0
92% is 92 out of 100
therefore simply put 92 over 100 and simplify it.
Meaning divide top and bottom into 2. Then you get your answer, if needed simplify again.
Answer:

Explanation:
We have been given with the quadratic equation 
We have general formula to find the roots of a quadratic equation first we find the discriminant with formula

and after that to find the variable suppose x we have the formula

And general quadratic equation is

On comparing the given quadratic equation with genral quadratic equation we will have values
a=1, b=-7 and c=-6
After substituting these values in the formula we will get

After substituting in the formula to find x we will get

Answer:
2500
Step-by-step explanation:
5^2(3+2+5)^2
5^2(10)^2
25(100)
=2500
