The function
is a parabola concave up, whose solutions are
from here, you can use the quadratic formula
to find that the solutions of the parabola are 
So, the parabola is positive if 
(which wouldn't make sense in our case) or

The remainder is always less than the divisor because if the remainder was more than the divisor then you would have a totally different answer. If the remainder was more than the divisor than you know your answers wrong.

Answer:
x = 8
Step-by-step explanation:
Firstly, create an equation or formula
- because they are congurent, IN = AT, so:
2x+10 = 26 (minus 10 from both sides)
2x = 16 (divide both sides by 2)
x = 8
Sub into the formula:
2 x 8 + 10 = 26
26 = 26
