Here are couple of observations, which should enable you to get your answer.

For the first one,

14+1x4+x=x+44x4+x=14xfor x≠−4

For the second one,

x+2−−−−−√−3x−7=x+2−−−−−√−3x−7×x+2−−−−−√+3x+2−−−−−√+3=(x+2−−−−−√)2−32(x−7)(x+2−−−−−√+3)=x+2−9(x−7)(x+2−−−−−√+3)=x−7(x−7)(x+2−−−−−√+3)=1x+2−−−−−√+3for x≠7
