Question

(5ײ-4×+7)-(3ײ+7×-2)​

Answer 1

Resposta:

$(x - 1) \times (2x - 9)$

Explicação passo-a-passo:

$(5x {}^{2} - 4x + 7) - (3x {}^{2} + 7x - 2) \\ 5x {}^{2} - 4x + 7 - 3x {}^{2} - 7x + 2 \\ 2x {}^{2} - 11x + 9 \\ 2x {}^{2} - 2x - 9x + 9 \\ 2x \times (x - 1) - 9(x - 1) \\ (x - 1) \times (2x - 9)$
