The question you posted was incomplete but i believe below is the complete question;
Let P2 denote the vector space of all polynomials with degree less than or equal to 2. (
a) Show that B = {1 + x + x 2 , 1 + 2x − x 2 , 1 − 2x − x 2} is a basis for P2.
(b) Find the coordinate vector of p(x) = 1 + 2x + 3x 2 relative to the basis B

Answer:
T = 36
Step-by-step explanation:
T = 5(4.2)-6(-2.5)
T = 21 + 15
T = 36
Answer:
=3y^2
Step-by-step explanation:
let,
length: x
width: y
According to condition,
x = 3y -----------(1)
Second condition
Perimeter = 2 (l + b)
80 = 2 (x + y)
x + y = 40 -------------(2)
To find area,
Area = L x B
=3y x y
= 3y^2
D -3m-4n+14. Once you write out the equation, you have to combine all the like terms, also known as simplifiying
