If x+1= 1 2+ 1 2+ 1 2+ where x (0,2 ) , then:

Options

  1. Asum of all the solutions of the equation is 3 .
  2. Bsum of all the solutions of the equation is 6 .
  3. Cnumber of solutions of the equation is 2 .
  4. Dnumber of solutions of the equation is 4 .

Correct answer

C. number of solutions of the equation is 2 .

Step-by-step solution

x+1= 1 2+ x+1 aligned & ( x+1)( x+3)=1 ^2 x+4 x+2=0 & ( x+2)^2=2 x=-2 2 & x=-2- 2 (rejected) & x=-2+ 2 (negative) + , 2 - aligned
