Answer 1

Given :

polynomial 3x (4x-5) +3

To Find : Value of polynomial if x = 2

21  

12

18

9​

Solution:

polynomial 3x (4x-5) +3

Substitute x = 2

= 3*2( 4 * 2 - 5)  + 3

= 6(8 - 5) + 3

= 6 (3) + 3

= 18 + 3

= 21

If x = 2, then the value of the polynomial 3x (4x-5) +3 will be 21

Answer 2

Given:

3x(4x-5)+3

To find:

if x=2, then the value of the polynomial 3x(4x-5)+3 will be?

Solution:

3x(4x-5)+3

Substitute the value of x=2 in the given polynomial.

$= > 3x(4x - 5) + 3$

$= > 3 \times 2((4 \times 2) - 5) + 3$

$= > 6(8 - 5) + 3$

$= > 6(3) + 3$

$= > 18 + 3$

$= > 21$

Hence, if x=2, then the value of the polynomial 3x(4x-5)+3 will be 21
