Could someone help me?

Factor -8x3-2x2-12x-3 by grouping what is the resulting expression?

(mc 02.03) what set of reflections and rotations would carry rectangle abcd onto itself? reflect over the y-axis, reflect over the x-axis, rotate 180° rotate 180°, reflect over the x-axis, reflect over the line y=x reflect over the x-axis, rotate 180°, reflect over the x-axis rotate 180, reflect over the y-axis, reflect over the line y=x

Which is f(5) for the function –2x2 + 2x - 3?
