#### Question

Find and correct the errors in the statement: (*z* + 5)^{2} = *z*^{2} + 25

#### Solution

L.H.S = (*z *+ 5)^{2} = (*z*)^{2} + 2(*z*)(5) + (5)^{2} [(*a* + *b*)^{2} = *a*^{2} + 2*ab* + *b*^{2}]

= *z*^{2} + 10*z* + 25 ≠ R.H.S

The correct statement is (*z *+ 5)^{2} = *z*^{2} + 10*z *+ 25
