Question 1: Factorize x 2 − 7 x + 12
Factorization exercises —
Solution:
Given types of mathematical expressions is;
i-e;
or
To factorize it we make two parts of the term in a way that if two parts are added together they will give us -7x — and if we multiply these two parts , their product will be
.
i-e -7x can be divided into -3x and -4x such that ;
1- when added i-e;
2- when multiplied such that;
So to factorize the type of mathematical expression we can write;
taking x common from first two terms and -4 from last two terms;
Can be written as;
Now (x-3) can be taken as common;
i-e
or
