Reduction of the equations to one of six standard forms (b,c >0) :
squares equal roots (ax2 = bx)
squares equal number (ax2 = c)
roots equal number (bx = c)
squares and roots equal number (ax2 + bx = c)
squares and number equal roots (ax2 + c = bx)
roots and number equal squares (bx + c = ax2)
Solve the equation x2+6x=7
The biggest change was the fact that the 2 and the 3 have been rotated through 90º.
If p is prime then 1+(p-1)! is divisible by p.
