Question

2|x+1|^2 -|x+1|=3 find value of x​

Answer 1

Answer:

x= -2

Step-by-step explanation:

2(x^2+1+2x)-x-1=3

2x^2+2+4x-x-1=3

2x^2+3x+1=3

2x^2+3x-2=0

2x^2+4x-x-2=0

2x(x+2)-1(x+2)=0

(2x-1)(x+2)=0

Answer 2

Step-by-step explanation:

2(x-1)^2-(x+1)=3

(2x-2)^2-(x+1)=3

4x^2-4x+4-x-1=3

4x^2-5x+3-3=0

4x^2-5x=0

4x^2=5x

4x=5

x=5/4
