Answer:

(c) x³ - 40x + 153x - 324

(d) 5x³y² - x³y³ + x²y⁴ + 5x²y - x²y² + x y³- 4xy - 4

Step-by-step explanation:

(c) (x - 36) × (x² - 4x + 9)

=> x³ - 4x² + 9x - 36x² + 144x - 324

= x³ + (- 36x²- 4x²) + ( 144x + 9x) - 324

= x³ - 40x + 153x - 324

(d) (xy + 1) × (5x²y - x²y² + xy³ - 4)

=> 5x³y² - x³y³ + x²y⁴ - 4xy + 5x²y - x²y² + x y³ - 4

There are no same degree elements to add or subtract.

So the answer is

5x³y² - x³y³ + x²y⁴ + 5x²y - x²y² + x y³- 4xy - 4
