Answer:

1. X² -2x-24= 0

2. X² -3x+2= 0

3. 2x² -7x -8= 0

4. 3x² + 38x +24= 0

Step-by-step explanation:

1.(-4,6)

(X+4)(x-6)= 0

X² -6x + 4x -24= 0

X² -2x-24=0

2.(1,2)

(X-1)(x-2)=0

X²-2x-x+2=0

X²-3x+2=0

3.(8,-1/2)

(X-8)(x+1/2)=0

X² +1/2x -8x -4=0

X² -7/2x -4=0

2x² -7x -8=0

4.(-2/3,-12)

(X+2/3)(x+12)=0

X² + 12x +2/3x + 8=0

3x² + 38x +24=0
