Can someone plz help me solved this problem! I’m giving you 10 points! I need help plz help me! Will mark you as brainiest!

a). 8(x + a)

b). 8(h + 2x)

Step-by-step explanation:

a). Given function is, f(x) = 8x²

    For x = a,

    f(a) = 8a²

    Now substitute these values in the expression,

    =

                  =

                  =

                  = 8(x + a)

b). =

                      =

                      =

                      = (8h + 16x)

                      = 8(h + 2x)
