Question

(x+1)²=-3x+5
me ajudem ​

Answer 1

Resposta: x'=-5+√41/2 x"=-5-√41/2

Explicação passo-a-passo:

(x+1)²=-3x+5

x²+2x+1=-3x+5

x²+2x+3x+1-5=0

x²+5x-4=0

Δ=b²-4.a.c

Δ=25-4.1.(-4)

Δ=25+16

Δ=41

x=-5±√41/2

x'=-5+√41/2 x"=-5-√41/2

Answer 2

(x + 1)² = -3x + 5  

Explicação passo-a-passo:

x² + 2x + 1 = -3x + 5

x² + 5x - 4 = 0

delta

d = 25 + 16 = 41

x1 = (-5 + √41)/2

x2 = (-5 - √41)/2
