Answer & Solution

Correct Answer

(D) 0

Step-by-step Solution

Detailed explanation

Given equation is \[ x^5+15 x^4+94 x^3+305 x^2+507 x+353=0 \] If all roots of the equation is increased by \(k\), then transformed equation is \[ \begin{aligned} (x-k)^5+15(x-k)^4+ & 94(x-k)^3+305(x-k)^2 \\ + & 507(x-k)+353=0 \ldots \end{aligned} \] for eliminate 4 th degree…
