Прошу решить подробно!!!
( 4x² - 7x + 3 ) √5x+6 = 0

Answer 1

$( 4x^2 - 7x + 3 )( \sqrt{5}x+6) = 0\\ \left[\begin{gathered} 4x^2 - 7x + 3=0\\ \sqrt{5}x+6 = 0 \end{gathered} \right.\\ \left[\begin{gathered} 4(x-1)(x-3/4)=0\\ \sqrt{5}x=-6 \end{gathered} \right.\\ \left[\begin{gathered} x=1\\ x=3/4=0.75\\ x=-6\sqrt{5}/5 \end{gathered} \right.$
