Enter the correct value so that each expression is a perfect-square trinomial.
x2 – 10x +

A = 25 so that the expression is a perfect-square trinomial.

Step-by-step explanation:

  Given : expression  

We have to find the value of A so that  each expression is a perfect-square trinomial.

perfect-square is the term in the form of

Since , we know the algebraic identity,

Given expression is of the form of

Thus, comparing , we get,

a= x ,

-2ab = -10x

⇒ b = 5

Thus adding b² term to get perfect-square trinomial.

b² = 25

Thus, the perfect-square trinomial becomes

So, A = 25

f(x) = y

f(-3) = -5
