Question

Determina as raizes

1/4x²=5x/4-6=0

Answer 1

d) 1/4x² + 5x/4 - 6 = 0
mmc = 4
x² + 5x - 24 = 0 <<<<<<<<<<<<<<<<
Delta = b² - 4ac
Delta = 25 - 4(1)(-24)
Delta = 25 + 96
Delta = 121

X = (-b +- raiz delta) / 2a
X = (-5 +- 11) / 2
x' = 6/2 = 3
x" = -16/2 = -8

Answer 2

Resposta:

Explicação passo-a-passo:

d) 1/4x² + 5x/4 - 6 = 0

mmc = 4

x² + 5x - 24 = 0 <<<<<<<<<<<<<<<<

Delta = b² - 4ac

Delta = 25 - 4(1)(-24)

Delta = 25 + 96

Delta = 121

X = (-b +- raiz delta) / 2a

X = (-5 +- 11) / 2

x' = 6/2 = 3

x" = -16/2 = -8

bons estudos!!!
