Multiple. (2x- y) (3x + y)

6x^2-xy-y^2

Step-by-step explanation:

if you want explanation then mark me thanks and follow me

We can use distributive properties 2 times.

First

(2x-y)(3x+y)

=2x(3x+y)-y(3x+y)

Then second time

=6x^2+2xy-3xy-y^2

Now combine like terms

=6x^2-xy-y^2

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
