Multiply:

5p²+ 25pq + 4q² by 2p² − 2pq +3q²

Simplify: (5a + 5b – c) (2b – 3c)

Simplify : (4x – 5y) (5x – 4y)

The adjacent sides of a rectangle are x² – 4xy + 7y² and x³ – 5xy². Find its area.

Multiply -4xy³ and 6x²y and verify your result for x = 2 and y= 1.

Evaluate: x(x – 5) + 2 for x = 1.

Evaluate: xy²(x – 5y) + 1 for x = 2 and y = 1.

Evaluate: 2x(3x – 5) – 5(x – 2) – 18 for x = 2.

Multiply and then verify :
−3x²y² and (x – 2y) for x = 1 and y = 2.

Multiply: (ab – 1) (3 – 2ab)
