The number of solutions of the equation ( ( 9 x - 9 x +2 ) ( 2 x - 7 x +3 )=0 ) is:

Options

  1. A2
  2. B3
  3. C1
  4. D4

Correct answer

D. 4

Step-by-step solution

Consider 1 x = x >0 aligned & 9 ^2-9 +2 2 ^2-7 +3 =0 & (3 -2)(3 -1)( -3)(2 -1)=0 & = 1 3 , 1 2 , 2 3 , 3 & x=9,4, 9 4 , 1 9 aligned So, no. of solutions =4
