Polynomial rectangle

If the length and width of a rectangle are (a2 - 6a + 4) and ( -2a2 - 9a + 3), find the area of the rectangle.

Correct answer:

A = 12 - 54 a + 49 a^2 + 3 a^3 - 2 a^4

Step-by-step explanation:

x= a2  6a + 4 y=2a2  9a + 3  A=x y A=(a2  6a + 4) ( 2a2  9a + 3) A=1254 a+49 a2+3 a32 a4
