The general form of an equation is
![A x^{2} +Bx+C=0](https://tex.z-dn.net/?f=A%20x%5E%7B2%7D%20%2BBx%2BC%3D0)
. Solving for (5+X)(5-X)=7 by multiplying the factors and subtratcting 7 on both sides gives the equation
![x^{2} -18=0](https://tex.z-dn.net/?f=%20x%5E%7B2%7D%20-18%3D0)
, so
A = 1
B = 0
C = -18
The square root of 64 is greater than the square root of 25; (square root sign) 64 > (square root sign) 25
