2x ² - 9x - 35
a + b = - 9
ab = 2 ( - 35 ) = - 70
1 , - 70
2 , - 35
5 , - 14
7 , - 10
1 - 70 = - 69
2 - 35 = - 35
5 - 14 = - 9
7 - 10 = - 3
a = - 14
b = 5
( 2x ² - 14x ) + ( 5x - 35 )
2x ( x - 7 ) + 5 ( x - 7 )
( x - 7 ) ( 2x + 5 )
( x + 1 ) ( x - 2 ) ( x + 3 )
( x ² - 2x + x - 2 ) ( x + 3 )
( x ² - x - 2 ) ( x + 3 )
x ³ + 3x ² - x ² - 3x - 2x - 6
x ³ + 2x ² - 3x - 2x - 6
x ³ + 2x ² - 5x - 6
hope helpful for you
