2X + 3 = 3x + 2 solution: 2x-2 = 3x-3 Deformation basis (?)?
Shift (both sides of the equation subtract 5)
If a = 4x square - 2x-1, B = 3x square - 2X-4, try to compare the size relationship between a and B
A-B
=4x²-2x-1-3x+2x+4
=x²+3
x²≥0
So x & sup2; + 3 ≥ 3 > 0
So A-B > 0
A>B
X - (2x-2 of x-1) + {3x-2 of 3 (X-2)}
X - (2x-2 of x-1) + {3x-2 of 3 (X-2)}
=x-3/2x+1+3x-3/2x+3
=x+4
