Solution:

Question 1.

  • (x - 2)(x + 3)
  • => x² + 3x - 2x - 6
  • => x² + x - 6

Question 2.

  • (x + 4)(x - 12)
  • => x² - 12x + 4x - 48
  • => x² - 8x - 48

Question 3.

  • (x + 3)(x + 4)
  • => x² + 4x + 3x + 12
  • => x² + 7x + 12

Question 4.

  • (x + 6)(x + 7)
  • => x² + 7x + 6x + 42
  • => x² + 13x + 42

Question 5.

  • (x + 8)(x + 9)
  • => x² + 9x + 8x + 72
  • => x² + 17x + 72

Question 6.

  • (x - 5)(x + 5)
  • x² + 5x - 5x - 25
  • => x² - 25

Question 7.

  • (x + 3)(x - 3)
  • => x² - 3x + 3x - 9
  • => x² - 9

Question 8.

  • (x + 10)(x + 10)
  • => x² + 10x + 10x + 100
  • => x² + 20x + 100

Question 9.

  • (x - 2)(x + 12)
  • => x² + 12x - 2x - 24
  • => x² + 10x - 24

Question 10.

  • (x + 4)(x - 3)
  • => x² - 3x + 4x - 12
  • => x² + x - 12

Question 11.

  • (x + 5)(x + 2)
  • => x² + 2x + 5x + 10
  • => x² + 7x + 10

Question 12.

  • (x - 3)(x - 4)
  • => x² - 4x - 3x + 12
  • => x² - 7x + 12

Question 13.

  • (x + 7)(x - 7)
  • => x² - 7x + 7x - 49
  • => x² - 49

Question 14.

  • (x - 6)(x + 3)
  • => x² + 3x - 6x - 18
  • => x² - 3x - 18

Question 15.

  • (x + 10)(x - 5)
  • => x² - 5x + 10x - 50
