Question

thực hiện phép tính :

( x - 2 ) * ( x^2 + 2x + 4 ) - ( x^3 + 5 )

Answer 1

\(\left(x-2\right)\left(x^2+2x+4\right)-\left(x^3+5\right)\)

\(=x^3-8-x^3-5\)

=-13

Answer 2

\(\left(x-2\right)\cdot\left(x^2+2x+4\right)-\left(x^3+5\right)\\ =x^2-8-x^3-5\\ =-13\)

Answer 3

Answer 4

(x³ - 2³)-(x³ + 5) = x³-2³-x³-5=8-5=3
