Answer:

1.x²+4x-16

2.x²-6x-72

3.x²+13x+36

4.x²+8x+12

5.x²+15x+54

6.x²+5x-20

7.x²-9

8.x²+20x+100

9.x²+9x-36

10.x²+x-12

11.x²+7x+10

12.x²-7x+12

13.x²-64

14.x²-3x-18

15.x²-4x-5

Step-by-step explanation:

1.(x - 2)(x + 8)

= x(x + 8)-2(x + 8)

= x²+8x-2x-16

=x²+4x-16

2.(x + 6)(x - 12)

=x(x -12)+6(x -12)

=x²-12x+6x-72

=x²-6x-72

3.(x + 9)(x + 4)

=x(x + 4)+9(x + 4)

=x²+4x+9x+36

=x²+13x+36  

4. (x + 6)(x + 2)

=x(x + 2)+6(x + 2)

=x²+2x+6x+12

=x²+8x+12

5. (x + 6)(x + 9)

=x(x + 9)+6(x + 9)

=x²+9x+6x+54

=x²+15x+54

6. (x - 4)(x+ 5)

=x(x + 5)-4(x + 5)

=x²+5x-4x-20

=x²+5x-20

7. (x + 3)(x - 3)

=x(x - 3)+3(x -3)

=x²-3x+3x-9    

=x²-9

8. (x + 10)(x + 10)

=x(x + 10)+10(x + 10)

=x²+10x+10x+100

=x²+20x-100

9. (x - 3)(x + 12)

=x(x + 12)-3(x + 12)

=x²+12x-3x-36

=x²+9x-36

10. (x + 4)(x - 3)

=x(x - 3)+4(x - 3)

=x²-3x+4x-12

=x²+x-12

11. (x + 5)(x + 2)

=x(x + 2)+5(x + 2)

=x²+2x+5x+10

=x²+7x+10

12. (x - 3)(x - 4)

=x(x -4)-3(x -4)

=x²-4x-3x+12

=x²-7x+12  

13. (x + 8)(x - 8)

=x(x - 8)+8(x - 8)

=x²-8x+8x-64

=x²-64

14. (x -6)(x+3)

=x(x + 3)-6(x + 3)  

=x²+3x-6x-18

=x²-3x-18

15. (x + 1)(x - 5)

=x(x - 5)+1(x - 5)

=x²-5x+x-5

=x²-4x-5
