Question

Which of the following constants can be added to x 2 - x to form a perfect square trinomial? 1

Answer 1

Given Equation is x^2 - x.

(1) Now, Take the middle term i.e 1.

(2) Divide it by 2

(3) Then Square it.


Now,

= > x^2 - x + (1/2)^2

= > x^2 - x + 1/4.

= > (x - 1/2)^2


Therefore the constant that can be added is (1/4).



Hope this helps!
