What are the possible numbers rational zeros of f(x) =x^4+2x^3-3x^2-4x+12

Which matrix multiplication is possible?

Can someone me i’m confused. will give brainliest and a whole bunch of points

Select the correct answer from the drop-down menu. subtracting 3xy^2 from 8xy^2 gives the same result as the expression. [tex]3xy ^{2} - 8xy ^{2} [/tex][tex] { - 7xy}^{2} - {2xy}^{2} [/tex][tex] {7xy}^{2} - {2xy}^{2} [/tex]
