Question

x2-4x+4=0 equação segundo grau​

Answer 1

x² - 4x + 4 = 0

a = 1

b = -4

c = 4

Δ = b² - 4. a. c

Δ = (-4)² - 4. 1. 4

Δ = 16 - 16

Δ = 0

x = -b ± $\sqrt{Triangulo}$ /2. a

x = -(-4) ± $\sqrt{0}$ /2. 1

x = 4 ± 0 /2

x¹ = 4 + 0 /2

x¹ = 4 /2 = 2

x² = 4 - 0 /2

x² = 4 /2 = 2

X = ( 2, 2)
