Risolvi le seguenti equazioni di primo grado usando i prodotti notevoli ove possibile:

SEMPLICE MEDIO DIFFICILE

$$\left( x-2\right) ^{2}=\left( x-1\right) ^{2}+5$$
$$\left( 3x-2\right) ^{2}+2x-1=\left( 2x+1\right) ^{2}+5x\left( x-2\right) -3$$
$$\left( 5x-1\right) ^{2}-7x\left( 3x-2\right) =\left( 2x-3\right) ^{2}$$
$$\left( 3x-4\right) ^{2}-3x\left( 3x-5\right) +2=0$$
$$\left( y+8\right) \left( y-8\right) =\left( y+8\right) ^{2}$$
$$\left( 2x+1\right) ^{2}-3\left( 2x-1\right) \left( 2x+1\right) =-2\left( 2x+1\right) \left( 2x-3\right)$$
$$\left( 2x-3\right) ^{2}-\left( x+3\right) \left( x-2\right) +5x=\left( x+4\right) \left( x-4\right) +3\left( x-2\right) ^{2}-4x^{2}-10x+4$$
$$\left( 2x-3\right) ^{2}-\left( 4x-1\right) \left( x+2\right) =\left( 3x-1\right) \left( 3x+1\right) -9x^{2}$$
