Question

Evaluate the expression when y=-4 y^2+5y+1

Answer 1

Explanation:

❀
`\underline{ \underline{ \text{Given}}} :`

• y = -4

❀
`\underline{ \underline{ \text{To \: find}}} :`

• Value of y² + 5y + 1

❀
`\underline{ \underline{ \text{Solution}}} :`

~Plug the value of y at first :

➾
`\sf{ {-4}^(2) + 5 * (-4 )+ 1}`

~ Evaluate the power : 4²

➾
`\sf{16 + 5 * (-4 )+ 1}`

Follow the BODMAS { Bracket , Of , Division , Multiplication , Addition and Subtraction } rule :

~Multiply -5 and 4

➾
`\sf{16 + (-20)+ 1}`

~ Multiply the signs : ( + ) and ( - ) :

➾
`\sf{16 - 20 + 1}`

~Add the numbers : 16 and 1

➾
`\sf{17-20}`

~ Subtract 20 from 17

➾
`\sf{-3}`

`\pink{ \boxed{ \boxed{ \tt{⟿ \: Our \: final \: answer : -3}}}}`

Hope I helped ! ♡

Have a wonderful day / night ツ
