Uknow what to do if not u get brainliest if first and right

Find the zero function by factoring (try to show work) h(x)=-x^2-6x-9

When the solutions to each of the two equations below are graphed in the xy-coordinate plane, the graphs of the solutions intersect at two places. write the y-cordninates of the points of intersection in the boxes below in order from smallest to largest. y=2x y=x^2-3
