1) [tex]\sf \boxed{1} \ x^2 + \boxed{2} \ x -24[/tex]

2) [tex]\sf \boxed{2} \ x^2+ \boxed{-1} \ x-15[/tex]

3) [tex]\sf \boxed{6} \ x^2+\boxed{19} \ x+10[/tex]

4) [tex]\sf \boxed{2} \ x^2+\boxed{-11} \ x+5[/tex]

solving step wise:

1)

  • (x+6)(x-4)
  • x² + 6(x) -4(x) -24
  • x² + 2(x) - 24

2)

  • (2(x)+5)(x-3)
  • 2(x)² - 6(x)+5(x)-15
  • 2(x)² - x - 15

3)

  • (3(x)+2)(2(x)+5)
  • 6(x)²+15(x)+4(x)+10
  • 6(x)² + 19(x)+10

4)

  • (2(x)-1)(x-5)
  • 2(x)² -10(x)-x+5
  • 2(x)² -11(x)+5

#1

  • (x+6)(x-4)
  • x(x-4)+6(x-4)
  • x^2-4x+6x-24
  • x^2+2x-24

#2

  • (2x+5)(x-3)
  • 2x(x-3)+5(x-3)
  • 2x^2-6x+5x-15
  • 2x^2-x-15

#3

  • (3x+2)(2x+5)
  • 3x(2x+5)+2(2x+5)
  • 6x^2+15x+4x+10
  • 6x^2+19x+10

#4

  • (2x-1)(x-5)
  • 2x(x-5)-1(x-5)
  • 2x^2-10x-x+5
  • 2x^2-11x+5
