Question 1:

$2x^(2) -x-15=0\\(2x+5)(x-3)=0$

Solutions are x = -5/2 and 3

Question 2:

$2x^2+11x =-5\\2x^2 + 11x +5 = 0\\(2x+1)(x+5)= 0$

Solutions are x = -1/2 and x =-5

Question 3:

$x^2-x-6=0\\(x-3)(x+2)=0$

Solutions are x = 3 and -2

Question 4

$x^(2) -3x-10 = 0\\(x-5)(x+2)=0$

Solutions are x = 5 and x = -2
