Question

SI ME LO RESUELVEN,LES DOY CORONA

Answer 1

Respuesta:

(2 © 5)*(X © 3) = - 120

(5 * 2) * (X * 3) = - 120

(5 - 2²) * (X - 3²) = - 120

( 5- 4) * ( X - 9). = - 120

1 * (X - 9) = - 120

1 - (X - 9)² = - 120

1 - (X² - 18X + 81) = - 120

1 - X² + 18X - 81 = - 120

- X² + 18X - 80 = - 120

- X² + 18X = -40

0 = X² - 18X - 40

X - 20

X +2

0 = (X - 20)(X + 2)

Entonces:

X - 20 = 0 y X + 2 = 0

X = 20 X = - 2

Hallar X>3: X = 20
