Question

(x - 3x + 2) (2x + 2​

Answer 1

Answer:

x =(2-√28)/6=(1-√ 7 )/3= -0.549

x =(2+√28)/6=(1+√ 7 )/3= 1.215

Answer 2

Answer:

Step-by-step explanation:

Given,

( x - 3x + 2 ) (2x +2 )

= x × 2x + x × 2 - 3x × 2x - 3x × 2 + 2 × 2x + 2 × 2

= 2x ^2 + 2x - 6x ^2 - 6x + 4x + 4

= 2x ^2 - 6x ^2 + 2x - 6x + 4x + 4

= -4x ^2 + 6x - 6x + 4

= -4x ^2 + 4 (+6x and -6x are cancelled )
