Question

usando a formula,resolva as eguaçoes

4xelevado a 2 -8x+4=0

Answer 1

4χ2-8x+4=0
a=4, b= -8, c=4
 Δ = 64-4*4*4
 Δ = 64-64
 Δ =0

X=+8+-0/2*4= 8+-0/8
Xl= 8+0/8         Xl= 1 

Xll= 8-0/8        Xll= 1

Answer 2

Ola Karem

4x² - 8x + 4 = 0

x² - 2x + 1 = 0

delta
d² = 4 - 4 = 0
d = 0

x = 2/2 = 1
