Question

(x + 4)(x – 2) = 6 + x(x – 5) ayudaaa con esto

Answer 1

Respuesta:

Explicación paso a paso:

(x + 4)(x – 2) = 6 + x(x – 5)

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

x²- 2x + 4x - 8 = 6 + x² - 5x

x² - x² - 2x + 4x + 5x = 6 + 8

x² = 0

- 2x + 4x + 5x = - 2x + 9x = 7x

6 + 8 = 14

7x = 14

x = 14 / 7

x = 2
