WebAnswer (1 of 4): With P(x)=x^6-x^5-x^3-x^2-x,\; Q(x)=x^4-x^3-x^2–1 We may write: P(x)=(x^2+1)Q(x)+R(x),\; R(x)=x^2-x+1 It is therefore sufficient to compute, for the roots z_j: \displaystyle \sum P(z_j)=\sum R(z_j) We also have: Q(x)=(x+1)T(x),\; T(x)=x^3–2x^2+x-1 One root is equal to -1 ... WebEquations which are reducible to quadratic : 2.1 Solve z4-z2+1 = 0. This equation is reducible to quadratic. What this means is that using a new variable, we can rewrite this equation as a quadratic equation Using y , such that y = z2 transforms the equation into : y2-y+1 = 0. Solving this new equation using the quadratic formula we get two ... tle8108 datasheet
