1. Decide whether the values given against each other are the solutions of that equation or not : (1) 5x + 4/2x + 1 = 2, x = 2, -2

1. Step-by-step explanation:

   p(x)=5x+4/2x+1=2

   p(2)=5(2)+4/2(2)+1=2

   =10+1+1=2

   12-2=10

   p(-2)=5(-2)+4/2(-2)+1=2

   -10+1+1=2

   -8=2

   -6

   p(0)=5(0)+4/2(0)+2=2

   =0+0+2=2

   2=2

   2-2=0

   there fore 0 is equal to 2
