Answer:
1. 6,-4,0
2. 1,0,-14
3. 2,5,-7
4. 1,3 1/2,-2
5. 2,14,0
Step-by-step explanation:
ax2+bx+c=0
1. 2x(3x-2)=0
2x(3x)-2x(2)=0
6x2-4x=0
2. (x+7)(x-7)=0
x(x)+x(-7)+7(x)+7(-7)=0
x2-7x+7x-14=0
x2+0x-14=0
3. 2x2+8x-3x=7
2x2+5x-7=0
4. (x+4)(x-1/2)=0
x(x)+x(-1/2)+4(x)+4(-1/2)=0
x2-1/2x+4x-2=0
x2+3 1/2x-2=0
5. (x+7)2x=0
x(2x)+7(2x)=0
2x2+14x=0
