Subtract: 4x from 8 - x

By how much is 3x³– 2x²y + xy² -y³ less than 4x³ – 3x²y – 7xy² +2y³

The perimeter of a triangle is 14a² + 20a + 13. Two of its sides are 3a² + 5a + 1 and a² + 10a – 6. Find its third side.

If x = 4a² + b² - 6ab; y = 3b² - 2a² + 8ab and z = 6a² + 8b² - 6ab find: x - y - z

Simplify: 4x + 7y - (5y - 8) - 2x
