Let f (x) = 14x3 + 28x2 - 46x and g (x) = 2x + 7. which is the solution set to the equation 1 12 f (x) = g (x) ?

1 12 f (x) = g (x)

or 112 * (14x3 + 28x2 - 46x) = 2x + 7

and 112 * (42 + 56 - 46x) = 2x + 7

112 * (98 - 46x) = 2x + 7

and 10.976 - 5.152x=2x+7

and - 5.152x-2x=7-10.976

we have - 5.154x = - 10.969

and x = 10.969/5154

Have fun
