Question 355517
{{{(4sqrt(x) + 2)^2}}}
One way to simplify this is to use FOIL. A faster way would be to use the pattern:
{{{(a + b)^2 = a^2 + 2ab + b^2}}}
In your expression, "a" is {{{4sqrt(x)}}} and "b" is 2. So by the pattern we get:
{{{(4sqrt(x))^2 + 2(4sqrt(x))(2) + 2^2}}}
which simplifies as follows:
{{{16x + 8sqrt(x) + 4}}}
(If you use FOIL, you should end up with the same thing.)
