    Add 136 to both sides

    5x^2 = 44 + 136

    Simplify 44 + 136 to 180

    Divide both sides by 5

    x^2 = 180/5

    Simplify 180/5 to 36

    x^2 = 36

    Take the square root of both sides

    x = ± √36

    Since 6 * 6 = 36, the square root of 36 is 6

    x = 6

    x=6

    Step-by-step explanation:

    5*x^2-136 - (44) = 0

    (5x^2-136) - 44=0

    5x^2-180=5 * (x^2-36)

    5 * (x+6) * (x-6) = 0

    x=6
