Explanation:
"since neither the numerator nor denominator can be"
"factored then fraction is described in simplest form"
rArr5/(7z+5)larrcolor(blue)" is in simplest form" The denominator cannot be zero as this would make the fraction undefined. Equating the denominator to zero and solving gives the value that z cannot be.
"solve "7z+5=0rArrz=-5/7larrcolor(red)" restricted value"
