Question

Perform the indicated operation: (x3 – 3x + 1) – (x3 + 7 – 12x).

Answer 1

Answer:

$\left( x^{3}-3x+1\right) -\left( x^{3}+7-12x\right)=9x - 6$

Step-by-step explanation:

$\left( x^{3}-3x+1\right) -\left( x^{3}+7-12x\right) = x^{3}-3x+1-x^{3}-7+12x$

                                                $= -3x+1-7+12x$

                                                $=9x - 6$
