Equation 1 :
[tex](3x + 2) {}^{2} = 2 {}^{2} (2x - 3) {}^{2} [/tex]
[tex](3x + 2) {}^{2} = (2(2x - 3) {}^{2} [/tex]
[tex](3x + 2) {}^{2} = (4x - 6) {}^{2} [/tex]
[tex]3x + 2 = 4x - 6 \: \: \: \\ ou \: \: \: 3x + 2 = - (4x - 6)[/tex]
[tex] \: \: \: x = 8 \\ ou \: \: \: 7x = 4[/tex]
[tex]x = 8 \: \: \: ou \: \: \: x = \frac{4}{7} [/tex]
