TīmeklisQuestion: Which equatise has rational rosts? x^(2)+8x-5=0 z^(2)+kx+9=0 2x^(2)+4z+5=0 3y^(2)+8x+4-0. Which equatise has rational rosts? x^(2)+8x-5=0 z^(2)+kx+9=0 2x^(2)+4z+5=0 3y^(2)+8x+4-0. Expert Answer. Who are the experts? Experts are tested by Chegg as specialists in their subject area. We reviewed their … Tīmeklisfirst do 11z*4z^2=44z^3 then 11z*-3z= -33z^2 and 11z*-4= -44z then -3*4z^2=-12z^2-3*-3z=9z-3*-4=12-2 terms in the first *3 terms in the second =6 terms altogether. The first and last are unique. There are two z^2 terms and two z terms. the answer is 44z^3-45z^2-35z+12 You can add terms only if the variable is the same
