Step-by-step explanation:

middle term splitting

Answer 2

Answer:

x = –3, 2

Step-by-step explanation:

2x² + 2x - 12

12×2 = 24

from factors of 24 we have to make 2

so, we can take 6,4

2x² + 6x – 4x - 12

now we will factorise it

= 2x( x + 3) - 4( x + 3)

= ( 2x – 4)(x + 3)

so we know that if we multiply anything with 0 it will be 0

so we will make 0 to both

so x = -3

(2x – 4)(– 3 + 3)

(2x – 4)(0)

= 0

now x = 2

(2(2) – 4)(x + 3)

( 4 – 4)(x + 3)

(0)(x + 3)

= 0
