Answer:
The common factor is (x3 – 4)(2x + 5)
Step-by-step explanation:
1. find gcf
2. factor out the gcf
3. use grouping
Answer:
[tex](x^3-4)(2x+5)[/tex]
Step-by-step explanation:
[tex]2x^4 + 5x^3 - 8x -20[/tex]
To factor this we use grouping method
[tex](2x^4 + 5x^3)+(- 8x -20)[/tex]
Take out GCF from each group. x^3 is the GCF for first group and -4 is the GCF from second group
[tex]x^3(2x+5)-4(2x+5)[/tex]
Now we factor out 2x+5
[tex](x^3-4)(2x+5)[/tex]
