Question

$u {}^{2} + 10u + 25$
​

Answer 1

u² + 10u + 25 = 0

FÓRMULA GENERAL

a = 1

b = 10

c = 25

u = -b ± √b² - 4ac / 2a

u = -10 ± √10² - 4 (1) (25) / 2(1)

u = -10 ± √100 - 100/2

u = -10 ± 0/2

u1 = -10 + 0/2 = -10/2 = -5

u2 = -10 - 0/2 = -10/2 = -5

Comprobación

u² + 10u + 25 = 0

(-5)² + 10 (-5) + 25 = 0

25 - 50 + 25 = 0

50 - 50 = 0

0 = 0

FACTORIZACIÓN

(u + 5)²

(u + 5) (u + 5)

u² + 5u + 5u + 25

u² + 10u + 25
