Question

Enter the correct value so that the expression is a perfect square trinomial x^2 - 10x +

Answer 1

25

Explanation:

The correct value can be calculated by doing (b/2)²

In this expression, it would be (-10/2)²

Which equals 25

Answer 2

x^2 -10x+25

Explanation:

Take the coefficient of x
