    Simplifying

    x2 + 8x = - 27

    Reorder the terms:

    8x + x2 = - 27

    Solving

    8x + x2 = - 27

    Solving for variable 'x'.

    Reorder the terms:

    27 + 8x + x2 = - 27 + 27

    Combine like terms: - 27 + 27 = 0

    27 + 8x + x2 = 0

    Step-by-step Factoring x2-8x+27

    The first term is, x2 its coefficient is 1.

    The middle term is, - 8x its coefficient is - 8.

    The last term, "the constant", is + 27

    Step-1 : Multiply the coefficient of the first term by the constant 1 • 27 = 27

    Step-2 : Find two factors of 27 whose sum equals the coefficient of the middle term, which is - 8.
