Simplify : (3y + 4z) (3y – 4z) + (2y + 7z) (y + z)

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 (x⁵) × (3x²) × (-2x) for x = 1.

Evaluate: (3x – 2)(x + 5) for x = 2.

Evaluate: xz (x² + y²) for x = 2, y = 1 and z= 1.

Evaluate: x(x – 5) + 2 for x = 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)
