The length 2

The length of a rectangle is 12y2 – 15y + 8 and the width is 7y – 11. Find the area of the rectangle

Result

S = (Correct answer is: 84 y^3 - 237 y^2 + 221 y - 88) Wrong answer

Solution:

a=12y215y+8 b=7y11  S=a b S=(12y215y+8) (7y11) S=7y (12y215y+8)11 (12y215y+8) S=84 y3237 y2+221 y88
