    All real values of x

    Step-by-step explanation:

    3 (12x²+x+1) + 12 (12x²+x+1) = 15 (12x²+x+1)

    (12x² + x + 1) (3+12) = 15 (12x²+x+1)

    15 (12x²+x+1) = 15 (12x²+x+1)

    Since both sides are identical, all real values of x will satisfy the equation

    infinite solutions

    Step-by-step explanation:

    3 (12x2+x+1) + 12 (12x2+x+1) = 15 (12x2+x+1)

    Combine like terms

    3 (12x2+x+1) + 12 (12x2+x+1) = 15 (12x2+x+1)

    15 (12x2+x+1) = 15 (12x2+x+1)

    Divide by 15

    (12x2+x+1) = (12x2+x+1)

    Since they are the same

    x can be any real value
