Answer 1

Resposta:

${(x + 1)}^{2} - {(2x + 3)}^{2} = 0 \\ (x + 1) \times (x + 1) - (2x + 3) \times (2x + 3) = 0 \\ {x}^{2} + x + x + 1 - {4x}^{2} + 6x + 6x + 9 = 0 \\ {x}^{2} - {4x}^{2} + x + x + 6x + 6x + 1 + 9 = 0 \\ - {3x}^{2} + 8x + 10 = 0 \\ \\ completa \\ \\ coeficientes \\ a = - 3 \\ b = 8 \\ c = 10$
