Question

3(2^x + 1) - 2^x+2 + 5 =0

Answer 1

Answer:

2(x-1)2-5=0  

Two solutions were found :

x =(4-√40)/4=1-1/2√ 10 = -0.581

x =(4+√40)/4=1+1/2√ 10 = 2.581

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 2 • (x - 1)2 -  5  = 0  

Step  2  :

2.1     Evaluate :  (x-1)2   =    x2-2x+1

Answer 2

6x^2+3-x^2+2+5=0

5x^2+10=
