How do you factor #5x^7-15x^6+20x^5#?

Answer 1

Ethan Adkins

Factor out the GCF

#5x^5(x^2 -3x + 4)#

This is all that we can do, since the trinomial inside the parentheses is non-factorable.

To factor the expression 5x^7 - 15x^6 + 20x^5, first, factor out the greatest common factor, which is 5x^5. This leaves you with 5x^5(x^2 - 3x + 4). Then, you can't factor the quadratic expression any further because it doesn't have real roots. So, the fully factored form is 5x^5(x^2 - 3x + 4).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
