Question

20. Find the value of x - x2 + x - 5 at X = 4
​

Answer 1

Answer:

Given that, x=4

then,

-  x-x2+x-5

-  4-4X2+4-5

-  4-8+4-5

-  4-(+12)-5

-   -13

(((-13is the answer)))

Answer 2

Answer:

- 5

Step-by-step explanation:

$\huge{ \boxed{ \boxed{ \underline{ \underline{\sf{GiveN }}}}}}$

• Value of x = 4

$\huge{ \boxed{ \boxed{ \underline{ \underline{\sf{To\:Find}}}}}}$

• x - 2x + x - 5

$\huge{ \boxed{ \boxed{ \underline{ \underline{\sf{ \star}{Solution}{ \star}}}}}}$

You can just substitute the value of x in x - 2x + x - 5

• x = 4

• 4 - 2 × 4 + 4 - 5

• 4 - 8 + 4 - 5

• Add all the positive integers and then add the negative integers

• 8 - 13

• -5
