Question

me a ajudem a resolver esta equação: x²(x²-2x+1)=-x(2x²-2x)

Answer 1

x4-2x3+x2=-2x3+2x2
x4-2x3+2x3+x2-2x2=
x4-x2
x2(x2-1)
x2=0
x2-1=0
x2=1
x=1

Answer 2

Ola Mahh

x²*(x² - 2x + 1) = -x*(2x² - 2x)

x²*(x² - 2x + 1) = x²*(2 - 2x)

x²*(x² - 2x + 1 +  2x - 2)

x² * (x² - 1) = 0

x1 = 0
x2 = -1
x3 = 1
