Answer:

Let \: f(x) =  {x}^{2}  - 5x + 3

Then \: f(3) =  {3}^{2}  - 5 \times 3 + 3

  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: =  \: 9 - 15  + 3

 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  =  9 - 12

 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  = - 3

for \: f(3) = 0 , 3 must \: be \: added \: to \:  \\ f(x)
