~Plug the value of y at first :
➾ [tex] \sf{ {-4}^{2} + 5 \times (-4 )+ 1}[/tex]
~ Evaluate the power : 4²
➾ [tex] \sf{16 + 5 \times (-4 )+ 1}[/tex]
Follow the BODMAS { Bracket , Of , Division , Multiplication , Addition and Subtraction } rule :
~Multiply -5 and 4
➾ [tex] \sf{16 + (-20)+ 1}[/tex]
~ Multiply the signs : ( + ) and ( - ) :
➾ [tex] \sf{16 - 20 + 1}[/tex]
~Add the numbers : 16 and 1
➾ [tex] \sf{17-20}[/tex]
~ Subtract 20 from 17
➾ [tex] \sf{-3}[/tex]
[tex] \pink{ \boxed{ \boxed{ \tt{⟿ \: Our \: final \: answer : -3}}}}[/tex]
