Answer:
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
Answer:
a and d
