<em><u>Factorization is:</u></em>
Given that we have to factor the given expressions
<h3><u>First expression:</u></h3>5x + 40
We have to take the greatest common factor out
When we find all the factors of two or more numbers, and some factors are the same then the largest of those common factors is the Greatest Common Factor
Take G.C.F of 5 and 40
The factors of 5 are: 1, 5
The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40
Then the greatest common factor is 5
Factor out 5 from given expression
7x - 49
Similarly, take G.C.F of 7 and 49
The factors of 7 are: 1, 7
The factors of 49 are: 1, 7, 49
Then the greatest common factor is 7
Factor out 7 from given expression
18x + 9
Similarly, take G.C.F of 18 and 9
The factors of 9 are: 1, 3, 9
The factors of 18 are: 1, 2, 3, 6, 9, 18
Then the greatest common factor is 9
Factor out 9 from given expression
15x - 10
Similarly, take G.C.F of 15 and 10
The factors of 10 are: 1, 2, 5, 10
The factors of 15 are: 1, 3, 5, 15
Then the greatest common factor is 5
Factor out 5 from given expression
Thus factorization is found
