Find a relation among the coefficient of polynomial
1. Find a relation among the coefficients of the polynomial p(x,y)=a+bx + cy + dx2 + exy +fy2 that makes it satisfy the potential equation. Choose a specific polynomial that satisfies the equation and show that, if Op/8x and 6p/ ay are both zero at some point, the surface there is saddle shaped

(5) (a) Let p(2) be a polynomial of the form r3 + ax2 + bx + c. What can you say about p() if you plug in a very, very large value for x? What about plugging in a very large negative number? (b) Give a justification for why p(x) must have a root. Hint: Try to draw it without drawing a root. (C) Show that every 3 x 3 matrix has an eigenvector. (d) Can you generalize your argument...

3(b) Although the polynomial z6-2c4 + x2 + 2 is not a cubic, use theorem 12.3.22 to show that it has no constructible roots. (The idea from this question can be used to do question 2(c)) Theorem 12.3.22: if a cubic equation with rational coefficients has a constructible root, then the equation has a rational root. 3.(c) The following polynomial is cubic but does not have rational coefficiens3. this polynomial (use part (b)) to show that this polynomial has no...
