    Answer:

    x = – 4, x = 9

    Step-by-step explanation:

    Given

    x² – 36 = 5x ( subtract 5x from both sides )

    x² – 5x – 36 = 0 ← in standard form

    Consider the factors of the constant term (- 36) which sum to give the coefficient of the x- term (- 5)

    The factors are – 9 and + 4, since

    – 9 × 4 = – 36 and – 9 + 4 = – 5, thus

    (x – 9)(x + 4) = 0

    Equate each factor to zero and solve for x

    x + 4 = 0 ⇒ x = – 4

    x – 9 = 0 ⇒ x = 9

    Answer:

    Step-by-step explanation:

    x ² – 36 = 5x

    x²-5x-36=0

    a=1  b= -5  c=-36

    calculate the discriminent b²-4ac ……continu
