\(3x^2+10x+7=0\)
\(\boxed{x=-1;\ -\frac73}\)\(x+7=2x-6,\ x\ne3\)
\(\boxed{x=13}\)\((x-9)(x+2)=0,\ x\ne0,-1\)
\(\boxed{x=-2;\ 9}\)\(\dfrac{(2x+3)(x-1)}{(3x+1)(x-1)}=0\)
\(\boxed{x=-\frac32}\)\((x-5)(x^2+9)=0\)
\(\boxed{x=5}\)\((x+2)(x-7)(x+7)=0\)
\(\boxed{x=-7;\ -2;\ 7}\)\((x-2)(2x^2+x+7)=0\)
\(\boxed{x=2}\)\((x-3)(4x^2-x+2)=0\)
\(\boxed{x=3}\)
