Ответ:

Объяснение:

5) 3$x^{2}$ - 8x + 5 = 3$x^{2}$ - 3x - 5x + 5 = 3x ( x - 1 ) - 5 ( x - 1 ) = ( x - 1 ) ( 3x - 5 )

6) 36$x^{2}$ - 12x + 1 = $6^{2}$ $x^{2}$ - 2 * 6x * 1 + $1^{2}$ = ( 6x $)^{2}$ - 2 * 6x * 1 + $1^{2}$ = ( 6x - 1 $)^{2}$

7) 2$x^{2}$ - 7x + 6 = 2$x^{2}$ - 3x - 4x + 6 = x ( 2x - 3 ) - 2 ( 2x - 3 ) = ( 2x - 3 ) ( x - 2 )
