Question

X^2-(m+1)x+m=0 td a resolução pir favor

Answer 1

x² - ( m +1)x + m = 0
a = 1
b = -( m + 1)
c = + m
DELTA = ( m+1)² - 4* 1 * m  = m² + 2m + 1 - 4m = m² - 2m + 1
m² - 2m + 1 = 0
( m + 1)² 
m + 1 = 0
m = -1 ****
x² - ( m+1)x + m = 0
x² - ( -1+1)x + (-1) = 0
x² - 0x - 1 = 0
x² - 1 = 0
x² = 1
x = +-1 ****
