Answer 1

Respuesta:

$- x^{2} + 4x - 3 \\ - x^{2} + 3x + x - 3 \\ - x(x - 3) + x - 3 \\ (x - 3)( - x + 1)$

$x^{2} - 2x + 1 = (x - 1)^{2}$

$4 {x}^{2} + x - 3 \\ 4 {x}^{2} + 4x - 3x - 3 \\ 4x(x + 1) - 3(x + 1) \\ (x + 1)(4x - 3)$

${x}^{2} + x + 1 \\ {x}^{2} + x + x + 1 - x \\ {x}^{2} + 2x + 1 - x \\ (x + 1 {)}^{2} - x$
