# What is the standard form of y= (3x^2-x+2)^2-x ?

$y = {\left(3 {x}^{2} - x + 2\right)}^{2} - x$
$y = \left(3 {x}^{2} - x + 2\right) \left(3 {x}^{2} - x + 2\right) - x$
$y = 3 {x}^{2} \left(3 {x}^{2} - x + 2\right) - x \left(3 {x}^{2} - x + 2\right) + 2 \left(3 {x}^{2} - x + 2\right) - x$
$y = 9 {x}^{4} - 3 {x}^{3} + 6 {x}^{2} - 3 {x}^{3} + {x}^{2} - 2 x + 6 {x}^{2} - 2 x + 4 - x$
$y = 9 {x}^{4} - 6 {x}^{3} + 13 {x}^{2} - 5 x + 4$
