Question

3 (x – 4)2 – 5 ( x – 4) = 12 then x = ____.​

Answer 1

Answer:

x = -8

Step-by-step explanation:

3x-12×2-5x+20=12

or, 3x-24-5x+20=12

or, -2x-4=12

or, -x=8

or, x=-8

Answer 2

Answer:

3(x–4)2 – 5(x–4) = 12

3*2(x-4) - 5(x-4) =12

6(x-4) - 5(x-4) =12

taking (x-4) as common,

(x-4)(6-5)=12

(x-4)(1)=12

x-4=12

x=12+4

x=16
