Splitting Fields : Find the splitting fields over Q for x^3+3x^2+3x-4.

Find the splitting fields over Q for x^3+3x^2+3x-4. Recall a splitting field is as follows: Let K be a field and let f(x)=a_0+a_1*x+...+a_n*x^n be a polynomial in K[x] of degree n>0. An extension field F of K is called a splitting field for f(x) over K if there exist elements r_1,r_2,...,r_n elements of F such that (i) f(x

Rectangular Kitchen Measured Cost

1st one: A family has a rectangular kitchen which measures 12 by 18 feet. They want to put diagonal heating coils in the floor of the room. How much will it cost them to put in the coils if they cost $25 foot? 12 x18 =216= Area 216x25= 5400 but since they want to put diagonals would I take half of this? 2nd one: A wi
