Question

x² + 11x + c find the value if c that would make this a perfect square trinomial

Answer 1

The expression is given as :

$x^2\text{ + 11x + c}$

The value of c is given as ; the value of the second term b divided by 2 then squared.

This means c = {b/2} ^2 ------- where b = 11

c = {11/ 2 } ^2

c =121/4
