Question
Simplify the following: $2 x^2+3 x\left(1-2 x^3\right)+x(x+1)$
✓
Answer
$2 x^2+3 x\left(1-2 x^3\right)+x(x+1)$
$=2 x^2+3 x-3 x \times 2 x^3+x^2+x$
$=2 x^2+3 x-6 x x^{(1+3)}+x^2+x$
$=2 x^2+3 x-6 x^4+x^2+x$
$=-6 x^4+3 x^2+4 x$
$=2 x^2+3 x-3 x \times 2 x^3+x^2+x$
$=2 x^2+3 x-6 x x^{(1+3)}+x^2+x$
$=2 x^2+3 x-6 x^4+x^2+x$
$=-6 x^4+3 x^2+4 x$
