Question 1:

  [tex]2x^{2} -x-15=0\\(2x+5)(x-3)=0[/tex]

   Solutions are x = -5/2 and 3

Question 2:

  [tex]2x^2+11x =-5\\2x^2 + 11x +5 = 0\\(2x+1)(x+5)= 0[/tex]

   Solutions are x = -1/2 and x =-5

Question 3:

 [tex]x^2-x-6=0\\(x-3)(x+2)=0[/tex]

  Solutions are x = 3 and -2

Question 4

  [tex]x^{2} -3x-10 = 0\\(x-5)(x+2)=0[/tex]

  Solutions are x = 5 and x = -2
