Use the formul

a (a+b)2=a2+2ab+b2 to expand the (4x+3y)2

Which is a true statement comparing the graphs of x^2/6^2-y^2/8^2 = 1 and x^2/8^2-y^2/6^2 the foci of both graphs are the same points. the lengths of both transverse axes are the same. the directrices of = 1 are horizontal while the directrices of = 1 are vertical. the vertices of = 1 are on the y-axis while the vertices of = 1 are on the x-axis.

Extra points! find the missing dimension! need asap

What value is a discontinuity of x squared plus 8 x plus 4, all over x squared minus x minus 6?
