Question

решите уравнение (x-2) (x-3)-12=(x-6)(x+1)

Answer 1

$(x - 2)(x - 3) - 12 = (x - 6)(x + 1) \\ x {}^{2} - 3x - 2x + 6 + ( - 12x + 72) \times (x + 1) \\ x {}^{2} - 3x - 2x + 6 - 12x {}^{2} - 12x + 72x + 72 \\ - 11x {}^{2} + 55x + 78$

Answer 2

х²-3х-2х+6+(-12х+72)•(х+1)
х²-3х-2х+6-12х²-12х+72х+72
-11х²+55х+78
