a) x² - 5 x + 4 = x² - x - 4 x + 4 = x ( x - 1 ) - 4 ( x - 1 ) = ( x - 1 ) ( x - 4 )
b ) x² - 5 x + 6 = x² - 3 x - 2 x + 6 = x ( x - 3 ) - 2 ( x - 3 ) = ( x - 3 ) ( x - 2 )
c ) x² - 7 x + 10 = x² - 2 x - 5 x + 10 = x ( x - 2 ) - 5 ( x - 2 ) = ( x - 2 ) ( x - 5 )
d ) x² - 10 x + 24 = x² - 4 x - 6 x + 24 = x ( x - 4 ) - 6 ( x - 4 ) = ( x - 4 ) ( x - 6 )
