# Note: Exercises preceded by an asterisk are of a more challenging nature.In Exercises 1 to 4, factor by using the GCF. 4 x + 12 y + 8 z

To determine

To factor:

To factor using the GCF.

4x+12y+8z

Explanation

Approach:

Factorizing a polynomial is to express the polynomial as a product of simpler expressions such that each of the simpler expressions divides the polynomial completely and also the product of all the simpler expressions gives the polynomial.

Calculation:

Given,

4x+12y+8z

First let us find the GCF of the terms in the above expression.

Thus, the GCF of the terms 4x, 12y and 8z is 2Â·2=4.

Thus, the given expression can be expressed as

=4x+12y+8z

=4Â·
