Question 1125691
[(x+4)-2y]^2
find the indicated products and simplify
<pre>Just FOIL since this involves the product of 2 binomials. ======> {{{matrix(1,11, "[", (x + 4) - 2y, "]"," "^2, or, "[", (x + 4) - 2y, "]", "[", (x + 4) - 2y,"]")}}}
This results in: {{{(x + 4)^2 - 4y(x + 4) + (2y)^2}}}, and then: {{{highlight_green(x^2 + 8x + 16 - 4xy - 16y + 4y^2)}}}
There are NO like-terms to combine, so that's it! Nothing else!
