Question

(x2 + x)2 - 8 (x2 + x) + 12 = 0​

Answer 1

Step-by-step explanation:

= (2x + 2) 2 - 8 (2x + x) + 12 = 0

2 - 8 (2x + x) + 12 = 0= (4x + 4) - (16x + 8x) + 12 = 0

(4x + 4) - (16x + 8x) + 12 = 0= (4x + 4) - ( 16x + 8x) = -12

(4x + 4) - ( 16x + 8x) = -12= (4x) - (16x + 8x) = -12-4

(16x + 8x) = -12-4 = (4x) - (16x + 8x) = -16

(4x) - (16x + 8x) = -16= (4x) - (24x) = -16

(4x) - (24x) = -16= -(20x) = -16

-(20x) = -16= -x = -16/20

-(20x) = -16= -x = -16/20= - x = -4/5

-(20x) = -16= -x = -16/20= - x = -4/5= x = -4/-5

= (x = 4/5 )

Answer 2

Step-by-step explanation:

$(2x + x)2 - 8(2x + x) + 12 = 0 \\ (4x + 2x)( - 16x - 8x) + 12 = 0 \\ (6x)( - 24x) + 12 = 0 \\ 6x - 24x = - 12 \\ - 18x = - 12 \\ x = - 12 \\ \frac{ - 12 }{- 18} = \frac{2}{3} \: \: \: \: answer \:$

so simple you can do this
