Answer 1

Resposta:

x'= -2  x''= -1/6

Explicação passo-a-passo:

$\frac{4x+6}{6} = \frac{(3x-2)^{2}+3x(1-5x) }{6}$

$4x+6=9x^{2} -12x+4+3x-15x^{2} \\\\4x+6=-6x^{2} -9x+4\\\\6x^{2} +9x+4x+6-4=0\\\\6x^{2} +13x+2=0\\\\x=\frac{-13+-\sqrt{13^{2}-48 } }{12} \\\\x=\frac{-13+-11}{12} \\\\x'= \frac{-13-11}{12} \\\\x'= -2\\\\x''= \frac{-13+11}{12} \\\\x''= \frac{-2}{12} \\\\x''= \frac{-1}{6}$
