Answer:
-10[tex]x^{7}[/tex][tex]y^{2}[/tex]
Step-by-step explanation:
12[tex]x^{4}[/tex]([tex]-\frac{5}{6} x^{3}[/tex][tex]y^{2}[/tex])
First multiply 12 * - [tex]\frac{5}{6}[/tex] , solving this you get -10
Next multiply [tex]x^{4}[/tex] by [tex]x^{3}[/tex] , solving this you get [tex]x^{7}[/tex]
Finally you have [tex]y^{2}[/tex], and nothing to multiply it by. So it stays as [tex]y^{2}[/tex]
Put is all together and you get -10[tex]x^{7}[/tex][tex]y^{2}[/tex]
