Hey ! there

Answer:

  • Option D. 39 is correct answer

Step-by-step explanation:

In this question we are given an expression that is x³ + x² + x and value of x is equal to 3 . And we are asked to find the value of expression when value of x is 3 .

Solution : -

[tex] \quad \dashrightarrow \qquad \: x {}^{3} + x {}^{2} + x[/tex]

Now substituting value of x as 3 in it ,

[tex] \quad \dashrightarrow \qquad \: 3 {}^{3} + 3 {}^{2} + 3[/tex]

[tex] \quad \dashrightarrow \qquad \: 27 + 9 + 3[/tex]

[tex] \quad \dashrightarrow \qquad \: 36 + 3[/tex]

[tex] \quad \dashrightarrow \qquad \: \blue{\underline{\boxed{\frak{39}}}} \quad \bigstar[/tex]

  • Henceforth , value of expression when x is equal to 3 is 39 .
  • Therefore , Option D is correct.

Hey mate ,

The equation given is x³+x²+x

  • It has asked what would be the value of equation if we substitute 3 as the value of x

There are many ways to solve the equation ,

Lets use the simple one ,

When we substitute 3 at the place of x , we get

= x³+x²+x

= 3³ + 3² + 3

= 27 + 9 + 3

= 39

When we substitute 3 at the place of x we get 39
