TOPIC 2: ALGEBRA ~ MATHEMATICS FORM 2
Once we learn some of the ‘tricks’ it becomes a fun challenge to work with our skills in solving each puzzle. So, Algebra is all about solving puzzles. In this
chapter we are going to learn some of the skills that help in solving mathematics puzzles.
operation of resolving a quantity into factors, when we expand
expressions, is done by removing the brackets. The reverse operation is
Factorizing and it is done by adding brackets.
factorization of 5a+5b, we have to find out a common thing in both
terms. We can see that the expression 5a+5b, have got common coefficient
in both terms, that is 5. So factoring it out we get 5(a+b).
18xyz-24xwz, we have to find out highest common factor of both terms.
Then factor it out, the answer will be 9xz(2y-3w).
we write the quadratic expression as a product of two factors we say
that we have factorized the expression. We are going to learn two
methods used to factorize quadratic expressions. These methods are
factorization by Splitting the middle term and factorization by
