Subtract: a² - 3ab - 6b² from 2b² - a² + 2ab

The perimeter of a rectangle is 28x³+ 16x² + 8x + 4. One of its sides is 8x² + 4x. Find the other side

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

If m = 9x² - 4xy + 5y² and n = - 3x² + 2xy - y² find: m + 2n

Simplify: 3(4y - 10) 2(y - 1)

Simplify: x - (x - y) - y - (y - x)

Multiply: 3x, 5x²y and 2y

Copy and complete the following multi-plication:

ax - b
× 2ax + 2b²

Evaluate: (a + 1)(a² - a + 1) and (a - 1)(a² + a + 1)

Simplify: `(5 ("x" - 4))/3 + (2(5x - 3))/5 + (6(x - 4))/7`
