Penjelasan dengan langkah-langkah:

1. 2y²+18y=0

2y(y+9)=0

y1= 0, y2=-9

HP={0,-9}

2. 3x²-24x=0

3x(x-8)=0

x1=0, x2=8

HP={0,8}

3. 4x²-64=0

4(x²-16)=0

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

x1=-4, x2=4

HP={-4,4}

4. 9x²-36=0

9(x²-4)=0

9(x+2)(x-2)=0

x1=-2, x2=2

HP={-2,2}

5. (x+1)²-25=0

x²+2x+1-25=0

x²+2x-24=0

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

x1=-6, x2=4

HP={-6,4}

6. 16x²-24x+9=0

(4x-3)²=0

4x=3

x=¾

HP={¾}

7. 4x²+16x+16=0

(2x+4)²=0

2x=-4

x=-2

HP={-2}

8. x²-10x+16=0

(x-2)(x-8)=0

x1=2, x2=8

HP={2,8}

9. x²+4x-21=0

(x+7)(x-3)=0

x1=-7, x2=3

HP={-7,3}

10. 3x²+17x+20=0

(3x+5)(x+4)=0

3x=-5, x2=-4

x1=-5/3

HP={-5/3,-4}

semoga membantu^^
