Use the FOIL method for multiplying two binomials.

The FOIL method gives the order in which you should multiply the terms in the two binomials.

$(6 x + y) (2 x + 8 y)$ $(6x+y)(2x+8y)$ =

$6 x \cdot 2 x + 6 x \cdot 8 y + y \cdot 2 x + y \cdot 8 y$ $6x*2x+6x*8y+y*2x+y*8y$ =

$12 x^{2} + 48 x y + 2 x y + 8 y^{2}$ $12x^2+48xy+2xy+8y^2$ =

$12 x^{2} + 50 x y + 8 y^{2}$ $12x^2+50xy+8y^2$
