1.

2x^3 - 11x^2 +44x +27 , if x = 25/3-4i

Answer»

2(25/3-4×3×2×1)=2(25/3-24)=2(24/-21)=2(-3)=-6

-6 is the correct answer

2(25/3-4×3×2×1)-11(25/3-4×3×2×1)+44(25/3-4×3×2×1)+27=2(25/3-24)-11(25/3-24)+44(25/3-24)=2(25/21)-11(25/3-24)+44(25/3-24)=50/21-275/21+44(25/21)=50-275+1100/21=875/21=41.66667
