Multiply: (X - A)(X + 3b)

Multiply: (x - a)(x + 3b)

Sum

(x - a)(x + 3b)

⇒ x (x + 3b) - a (x + 3b)

⇒ x² + 3bx - ax - 3ab

Factorize a² + 4b² - 4ab - 4c²

Factorize the following expressions:

a³ + b³ + a + b

Factorize 8a³+ 27b³ + 36a²b + 54ab²

`1/27 x^3 - y^3 + 125z^3 + 5xyz`

If x³ − 3x² + 3x − 7 = (x + 1) (ax² + bx + c), then a + b + c =

Write the number of the term of the following polynomial.

ax – by + y x z

Evaluate: (a² + 2ab + b²)(a + b)

Multiply: (2x - 3y)(2x + 3y)

Divide: x² + 4xy + 4y² by x + 2y
