--- Trinomial

--- Binomial

Step-by-step explanation:

Given

Solving (a): Perfect square trinomial

We have:

Express as an equation

Start----------------------------

Take coefficient of n i.e. (2/3)

Half it: i.e. (1/3)

Square it: (1/63^2

Add to both sides of the equation

---------------------------End

So, we have:

Remove brackets

Solving (b): Binomial Squared

Expand

Factorize:

Factor out n + 1/3

Express as square

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
