The missing term in the given perfect square trinomial is 28.
Given,
The perfect square trinomial = 4x² + x + 49.
To Find,
The missing term.
Solution,
In this question,
We will use the identity,
(a+b)² = a² + 2ab + b²
Now, we will solve the question using this identity,
= 4x² + x + 49
= (2x)² + 2 × 2x × 7 + 49.
= (2x)² + 28x + 49
= (2x +7)²
The missing term in the given perfect square trinomial is 28.
