If x = 5,

5(x^2) -(2x)+5

= 5(25) -10+5

=(125-10)+5

=115+5

=120

Answer:

when x = 5, the value of the expression 5x^2 - 2x + 5 is 125.

Explanation:

To find the value of the expression 5x^2 - 2x + 5 when x = 5, we simply substitute 5 for x and evaluate:

5x^2 - 2x + 5

= 5(5)^2 - 2(5) + 5 (substituting x = 5)

= 5(25) - 10 + 5

= 125 - 10 + 5

= 120 + 5

= 125

Therefore, when x = 5, the value of the expression 5x^2 - 2x + 5 is 125.
