(12x284)(2x+5)

Explanation:

Let's start with what we got:

24x3+60x2168x420

What we can do is break it up into:

24x3+60x2 & 168x420

We will factor this by grouping, find the GCF for each of them:

The GCF for 24x3+60x2 is 12x2

The GCF for 168x420 is 42

Now let's factor them:

24x3+60x212x2(2x+5)
168x42084(2x+5)

We can see that 12x284 is one factor the other one is 2x+5

Our final answer is (12x284)(2x+5)

2(2x+5)(2x27)

Explanation:

f(x)=12(2x3+5x214x35)=12y
Facrybygrouπng:
y=2x2(x+5)7(2x+5)=(2x+5)(2x27)
f(x)=12(2x+5)(2x27)
