Question

AYUDA POR FAVOR ME URGE UN POCO ​

Answer 1

Explicación paso a paso:

● 1) x^2 + 11 = 92

x^2 = 92 - 11

x ^2 = 81

x = 9

● 2) x² - 15 = 106

x² = 106 + 15

x² = 121

x = √121

x = 11

● 3) x + x² = 182

x² + x - 182 = 0

(x - 13)(x + 14) = 0

x - 13 = 0

x = 13 => Solución 1

x + 14 = 0

x = -14 => Solución 2

● 4) x² - x = 210

x² - x - 210 = 0

(x - 15) (x + 14) = 0

x - 15 = 0

x = 15 => Solución 1

x + 14 = 0

x = - 14 => Solución 2

● 5) x² + 2x = 80

x² + 2x - 80 = 0

(x - 8)(x + 10) = 0

x - 8 = 0

x = 8 => Solución 1

x + 10 = 0

x = -10 => Solución 2
