Question

Place the indicated product in the proper location on the grid.

(4ya - 6xb)(4ya + 6xb)

Answer 1

Ok.

Answer 2

I don't really understand your question
What grid?

(4ya - 6xb)(4ya + 6xb} = 16(ya)² -36(xb)²
\[\frac{ y^2 }{ (1/4)^2 }-\frac{ x^2 }{ (1/6)^2 }\]

if you would put it on a grid with ya axis as an y-axis and xb as an x-axis and you equate it to a value, say 1
you get an hyperbola

\[\frac{ y^2 }{ (1/4)^2 }-\frac{ x^2 }{ (1/6)² }=1\]
