Answer:
well a perfect square of trinomial if it can be factored into a binomial multiplied to itself. so theres step by step to
Step-by-step explanation:
For example, in the trinomial x2 - 12x + 36, both x2 and 36 are perfect squares.welcome
Answer is... X=25
........
Note what i actually represents.
i is the very basis of a whole new level of counting. When finding discriminants, we often say that a quadratic has no
real roots if the discriminant is 0. Needless to say, there are roots, they are just imaginary.

, in real terms, is non-existent. That is, there are no numbers in the real number system that when multiplied by itself produces a result of -1. This is what i unit represents.
Let's tackle this problem in smaller steps.
Let's first expand our brackets.
(i - 7i)² = (-6i)² = 36i²
Now, let's distribute the xi.
xi(i - 7i)² = xi(36i²) = 36xi³ =

= -36xi
