Question

1. (x + 2)²= 32 + (x - 2)²

2. (x + 3)²= (x + 2)²+ 17

3. (x + 2)²– x = 2x²– (x - 2)²

4. (x + 6)² + 12 = x² + 3x + 1

5. (x - 5)² + 4 = x²– 7x


6. (x + 4)(x + 5) = (x + 2)(x + 6)

7. (x + 6)(x + 1) = (x + 2)(x + 3)

8. (x + 5)(x – 5) – x² = -2x + 25

9. (x + 5)(x - 3) = x² + x + 1

10. (x - 4)(x - 3) = x² + 2x + 8


11. (x + 3)(x² – 3x + 9) = 91

12. (x - 4)(x² + 4x + 16) = 936

13. (x + 8)(x²+ 8x + 64) – x² = 2x

14. (x - 2)(x² + 2x + 4) – x³= 8x

15. (x + 5)(x²– 5x + 25) – (x - 3)(x²+ 3x + 9) = 49x

Answer 1

Explicación paso a paso:

1)

$(x + 2) {}^{2} = x {}^{2} + 4x + 4$

$(x - 2) {}^{2} = x { }^{2} - 4x + 4$

Reemplazando en

$(x + {2)}^{2} = 32 + (x - 2) {}^{2}$

$x {}^{2} + 4x + 4 = 32 + x {}^{2} + - 4x + 4$

$8x = 32$

$x = 4$
