    \[f\circ g\] or \[f\times g\]?

    what is ` (4x²-3) × (-3x²+4) ` ?

    the first part, the `4x²-3` is f, and the second part, the `-3x²+4 `, is the g. that is what they mean by f × g

    all I am trying to say that in the following case, \(\large\color{black}{ \displaystyle f(x)=4x^2-3 ~~~~{\rm and}~~~~ g(x)=-3x^2+42}\) the (f×g)(x) is going to be \(\large\color{black}{ \displaystyle (f×g)(x)=\left(4x^2-3\right)\times \left(-3x^2+42\right)}\)

    so you are to multiply what f(x) is equal to, BY what g(x) is equal to.

    8x³-12x² it would be for the problem you posted just now

    i suggest to go back and review multiplication of variables with different coefficients and powers, factoring and all that.
