    30 increased by 3 times the square of a number

    The phrase a number means an arbitrary variable, let's call it x
    x

    The square of a number means we raise x to the power of 2:
    x^2

    3 times the square:
    3x^2

    The phrase increased by means we add 3x^2 to 30:
    30 + 3x^2
