The 7th degree polynomial x^7 - 3x^6 - 7x^4 + 21x^3 - 8x + 24 has a factor (x - 3) (a) Divide x^7 - 3x^6 - 7x^4 + 21x^3 - 8x + 24 by x - 3 and thus: (b) Express it in the form (x - 3)(ax^6 + bx^3 + c) (c) By putting Z = x^3, find all the factors, real or complex of the 6th degree polynomial and thus: (d) Expres
Please see attached PDF file; I'm trying to derive a couple of results involving Lagrange multipliers and a linear algebra equivalence. This makes use of the extension to Lagrange multipliers whereby the constraint is an inequality (see, e.g., section 5.1 of http://www.cs.berkeley.edu/~klein/papers/lagrange-multipliers.pdf ).

I have 400 feet of lumber to frame a rectangular patio. I want to maximize the area of the patio. What should the dimensions of th patio be. Show how the maximum area of patio is calculated from the algebraic equation. Use the vertex form to find the maximum area.
When using the quadratic formula to solve a quadratic equation ax^2 + bx + c = 0, the discriminant is b2 - 4ac. This discriminant can be positive, zero, or negative. (When the discriminant is negative, then we have the square root of a negative number. This is called an imaginary number, sqrt(-1) = i. ) Explain what the value
