(2x2 + x − 3 )(x − 1.)
= 4x3 + x2 - 3x - 2x2 - x + 3
= 4x3 - x2 - 4x + 3

A similar triangle means it is of a diferent size, but the sides or angles are proportionaly the same.
Use the rule of 3 on each number, to find the equivalent sides:
65 - 39
60 - x
(60 * 39) / 65
2340 / 65
36cm
60 - 36
25 - x
(25*36) / 60
900 / 60
15cm
Original triangle: 65, 60, 25
Similar triangle: 39, 36, 15
