    Answer:

    x= -3

    Step-by-step explanation:

    mark branliest pls

    Standard form:

    2×2 − 18 = 0

    Factorization:

    2(x + 3)(x − 3) = 0

    Solutions based on factorization:

    x + 3 = 0   ⇒   x1 = −3

    x − 3 = 0   ⇒   x2 = 3

    Extrema:

    Min = (0, −18)

    Answer:

    x = ± 3

    Step-by-step explanation:

    Given

    2x² – 5 = 13 ( add 5 to both sides )

    2x² = 18 ( divide both sides by 2 )

    x² = 9 ( take the square root of both sides )

    x = ± \sqrt{9} = ± 3

    smaller solution is x = – 3

    larger solution is x = 3
