Sagot :

RedRicin
Factor out the GCF of [tex]21x^3+24x^2-12x[/tex]

Take a look at the coefficients. Think about their prime factorization.
Each of these has 3 as a factor, so that can be taken out.

[tex]3(7x^3+8x^2-4x)[/tex]

Looking now at the variables, you might notice each has x as a factor.
Let's take that out.

We are left with our final answer [tex]\boxed{3x(7x^2+8x-4)}[/tex]
Panoyin
21x³ + 24x² - 12x
3x(7x²) + 3x(8x) - 3x(4)
3x(7x² + 8x - 4)
3x(7x² + 4(2x) - 2(1))
3x(7x² + 4(2x - 1))
