Question

$( {2x}^{2} - x + 3)( {2x}^{2} - 2x + 2)$
​

Answer 1

$(2 {x}^{2} - x + 3) \times (2 {x}^{2} - 2x + 2)$

$(2 {x}^{2} (2 {x}^{2} - 2x + 2) - x \times (2 {x}^{2} - 2x + 2 + 3(2 {x}^{2} - 2x + 2)$

$4 {x}^{4} - 4 {x}^{3} + 4 {x}^{2} - 2 {x}^{3} + 2 {x}^{2} - 2x + 6 {x}^{2} - 6x + 6$

$4 {x}^{4} - 6 {x}^{3} + 12 {x}^{2} - 8x + 6$

Как-то так...
