1) ( 2x + 3 )( 2x - 3 )
= 4x² + 6x - 6x - 9
= 4x² - 9

2) ( 2x + 5 ) ( 2x - 5 )
= 4x² - 10x + 10x - 25
= 4x² - 25

3) ( 3x + 7 )( x - 6 )
= 3x² + 7x - 18x - 42
= 3x² - 11x - 42

4) ( 3x + 1 ) ( 3x - 2)
= 9x² + 3x - 6x - 2
= 9x² - 3x - 2

5) ( 3x + 1 )( 3x + 2 )
= 9x² + 3x + 6x + 2
= 9x² + 9x + 2

6) ( 2x + 7 )(6x - 4 )
= 12x² + 42x - 8x - 28
= 12x² + 36x - 28

7) ( 2x + 7 )( 6 + 4x)
= 12x + 42 + 8x² + 28x
= 8x² + 40x + 42

8) ( 2x + 7 )( 6 - 4x )
= 12x + 42 - 8x² - 28x
= - 8x² - 16x + 42

9) ( 2x - 7 )( 6 + 4x )
= 12x - 42 + 8x² - 28x
= 8x² - 16x - 42

10) ( 2x - 7 )( 6 - 2x )
= 12x - 42 - 4x² + 14x
= - 4x² + 26x - 42

Jawabannya:

2. (2x+5)(2x-5)
= 4x^2-10x+10x-25
= 4x^2-25

4. (3x+1)(3x-2)
= 9x^2+3x-6x-2
= 9x^2-3x-2

3. (3x+7)(x-6)
= 9x^2+3x-6x-2
= 9x^2-3x-2

1. (2x+3)(2x-3)
= 4x^2+6x-6x-9
= 4x^2-9

5. (3x+1)(3x+2)
= 9x^2+3x+6x+2
= 9x^2+9x+2

6. (2x+7)+(6x-4)
= 12x^2+43x-8x-28
= 12x^2+36x-28

7. (2x+7)(6+4x)
= 12x+42+8x^2+28x
= 8x^2+40x+42

8. (2x+7)(6-4x)
= 12x+42-8x^2-28x
= -8x^2-16x+42

9. (2x-7)(6+4x)
= 12x-42+8x^2-28x
= 8x^2-16x-42

10. (2x-7)(6-2x)
= -4x^2+26x-42
