Given the polynomials A(x)=2x4−x3+4x−9A(x)=2x^{4}-x^{3}+4x-9, B(x)=x4+3x3−2x2+5B(x)=x^{4}+3x^{3}-2x^{2}+5, and C(x)=5x3−4x2+x−2C(x)=5x^{3}-4x^{2}+x-2, answer the following. (i) Form the expression T(x)=A(x)−2[B(x)−C(x)]T(x)=A(x)-2\bigl[B(x)-C(x)\bigr]. (ii) Simplify T(x)T(x) completely, combining all like terms. (iii) Evaluate T(1)T(1) using your simplified expression from part (ii).
