Like terms can be added or subtracted whereas unlike terms cannot.

The numerical factor of the given variable is called coefficient of the term. (Take x common)

keeping blank on one side and all other terms on other side add like terms

term would contain only (\\( u\\times u \\)) of variable u and coefficient is group of factors of same term except \\(u^{2}\\)

product of separate factors gives a term, where \\(5\\times 1=5 \\) is also a separate term

5 times of y gives \\(5\\times y \\) as one of the term of required expression

perimeter is the sum of all sides

x multiplied by itself and product of x and y gives two individual terms of an expression

term of all factors except x

area of triangle= \\( \\frac{1}{2}\\times height\\times base\\), where height = base = m
