♪Answer :

»x² - 3x + 27 = 6x + 7

  • ax² + bx + c = 0

»x² - 3x + 27 - 6x - 7 = 0

»x² - 9x + 20 = 0

»(x - 4)(x - 5) = 0

»(x - 4) = 0 V (x - 5) = 0

  • For [tex]\tiny x_1[/tex]

»x - 4 = 0

»x = 0 + 4

»x = 4

  • For [tex]\tiny x_2[/tex]

»x - 5 = 0

»x = 0 + 5

»x = 5

  • x = {x| 4 or 5, x€R}
