Given the following perfect square trinomial, fill in the missing term. x2 - 16x + ____
Solution:
A perfect square trinomial is of the form
(a - b)2 = a2 - 2ab + b2 --- (1)
Given, the equation is x2 + 12x +__
Let us take the missing term as c,
Now, x2 - 16x + c --- (2)
Comparing (1) and (2), we get,
a2 = x2
a = x
-2ab = -16x
We know, a = x
So, 2xb = 16x
2b = 16
b = 16/2
b = 8
b2 = c
c = (8)2
c = 64
Therefore, the missing term is 64.
Given the following perfect square trinomial, fill in the missing term. x2 - 16x + ____
Summary:
The missing term to be added to x2 - 16x to form a perfect square trinomial is 64.
