Me ajudammm pfvr e pra amanhã!!!!!​

Answer 1

Resposta:

A

(2x + 1)(2x + 1) + (x - 5)(x - 5) = 0

4x² +2x + 2x + 1 + x² - 5x - 5x + 25 = 0

5x² - 6x + 26 = 0

B

(x - 1)(x - 1) - (x + 1)(x + 1) =0

(x² - x - x + 1) - (x² + x + x + 1) = 0

x² - 2x + 1 - x² - 2x - 1 = 0

-4x = 0

C

(x² - 3x)(x² - 3x) - (4x + 2)(4x + 2) = 0

(x⁴ - 3x³ - 3x³ + 9x²) - (16x² + 8x + 8x + 4) = 0

x⁴ - 6x³ + 9x² - 16x² - 8x - 8x - 4 = 0

x⁴ - 6x³ - 7x² - 16x - 4 = 0

Qualquer Dúvida, Chama!!
