Question 33885
{{{(9x-4.1)^2(7x-5.4)}}}
You cannot use the property of distributive for the exponent.
(9x-4.1)^2
is the same as:
(9x - 4.1)(9x - 4.1)
81x^2 - 36.9x - 36.9x + 16.81
81x^2 - 73.8x + 16.81
:so:
{{{(81x^2 - 73.8x + 16.81)(7x - 5.4)}}}
That is your answer.... To simplify further, I will let you foil it.
