Fill the blank with a number to make the expression a perfect square v^2-10v+

Sagot :

9514 1404 393

Answer:

  25

Step-by-step explanation:

To make this expression into a perfect square trinomial, we must add the square of half the coefficient of the linear term.

  v^2 -10v +(-10/2)^2 = v^2 -10v +25

The missing constant is 25.
