SOLUTION

TO DETERMINE

Expand using identities :

  \sf  {(x - 5)}^{2}

CONCEPT TO BE IMPLEMENTED

We are aware of the formula that

  \sf  {(a - b)}^{2}  =  {a}^{2}  - 2ab +  {b}^{2}

EVALUATION

Here the given expression is

  \sf  {(x - 5)}^{2}

We now use the formula

 \boxed{ \:  \:   \sf  {(a - b)}^{2}  =  {a}^{2}  - 2ab +  {b}^{2}  \:  \: }

We have

  \sf  {(x - 5)}^{2}

  \sf  =  {x}^{2}   - 2.x.5 +  {5}^{2}

  \sf  =  {x}^{2}   - 10x + 25
