Algebra/Calculus Questions?

Question

Please also show me the steps in order for me to understand it.

1. Solve x^4 + x^3 + 2x^2 + 4x - 8 = O

2. Factor x^3 - 9x^2 + 3 + 20x - 12

I don't know how to start with this solving.

3. Find the quadratic formula that has a Vertex of (2, 4) and passes through point (4, 2)

For this I was able to figure the equation for the Vertex but it did not pass through the point named.

Thank you.

This is the homeschool forum, not the homework help forum.

If you're a homeschooler, go ask your mom or dad.
