Answer:
[tex]36xy^2 + 8x^2 + 27y^2 + 6x[/tex]
Step-by-step explanation:
Use the FOIL method of multiplying binomials.
First term in each binomial: [tex]-2x * -4x = 8x^2[/tex]
Outside terms: [tex]-2x * -3 = 6x[/tex]
Inside terms: [tex]-9y^2 * -4x = 36xy^2[/tex]
Last term in each binomial: [tex]-9y^2 * -3 = 27y^2[/tex]
Now, rearrange the terms correctly. [tex]36xy^2 + 8x^2 + 27y^2 + 6x[/tex]
This is our final answer, since it can not be simplified any more.
