Question

2x2 -9x - 35
(x+1) (x - 2) (x +3​

Answer 1

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
