Respuesta :

if you meant that then, you would do this. turn it into  4x^2+10x+2x+4. the factor out the 2x which would be 2x(2x+5)+2x+5 and then factor the 2x+5 which would become (2x+5)x(2x+1)

So for this, I will be factoring by grouping. Firstly, what two terms have a product of 20x² and a sum of 12x? That would be 2x and 10x. Replace 12x with 2x + 10x:

[tex]4x^2+2x+10x+5[/tex]

Next, factor 4x² + 2x and 10x + 5 separately. Make sure that they have the same quantity inside the parentheses:

[tex]2x(2x+1)+5(2x+1)[/tex]

Now you can rewrite the expression as [tex](2x+5)(2x+1)[/tex] , which is your final answer.
