Answer 2

Answer:

1) x = -2 , 4

2) x = -1 , 4/3

Step-by-step explanation:

1) x2 - 2x - 8

mid term split

=> x2 - 4x + 2x - 8

=> x(x - 4 ) + 2(x - 4)

=> (x +2) (x - 4)

therefor, x = -2, 4

2) 3x2 - 2x - 4

mid term split

=> 3x2 +3x - 4x - 4

=> 3x(x + 1) - 4(x + 1)

=>(3x - 4) (x +1)

therefor , x = 4/3 , -1
