If h(x) divides g(x) in Q[x], show that h(x) divides g(x) in Z[x].arrow_forwardX1 + x2 X2 - X3 X1 + 2x4 [x2 – x3 + 3x4] 8. Determine [T]B if T and B = 1arrow_forward
- This is a question from a linear algebra course: Let V = R[X]3, the polynomials of degree at most three, and B = {1, X, X2, X3}. Show what the image under fB is of:• the four basic elements: P1(X) = 1, P2(X) = X, P3(X) = X2 and P4(X) = X3• P(X) = 2 + 6X + 3X2 + 4X3arrow_forwardf(x)=x(40-x)/(20+9cos(x)) Let the function and the set V=[10,15,20,25,30]. Consider the set W of pairs (x,f(x)) where x belongs to V. Interpolate the points in W through a polynomial q(x) and give q(27.7) as an answer.arrow_forward[X1 + x3 X2 - X3 [2x1-x21 7.
