Factorize x² - y² - 4xz + 4z²

Factorize the following expressions:

32a³ + 108b³

Factorize the following expressions:

(a + b)³ – 8(a – b)³

8x³ + 27y³ - 216z³ + 108xyz

(a – 3b)³ + (3b – c)³ + (c – a)³

If (x + y)³ − (x − y)³ − 6y(x² − y²) = ky², then k =

Separate monomials, binomials, trinomials and polynomials from the following algebraic expressions :

8 − 3x, xy², 3y² − 5y + 8, 9x − 3x² + 15x³ − 7,
3x × 5y, 3x ÷ 5y, 2y ÷ 7 + 3x − 7 and 4 − ax² + bx + y

Evaluate: (a² + b² + c² - ab - bc - ca)(a + b + c)

Write the coefficient of x² and x in the following polynomials

πx² – x + 2

When y = –1, the value of the expression 2y – 1 is 3
