Factor this trinomial fast please!

x2 - 11x + 30

If δmtv is reflected across the y-axis, what are the resulting coordinates of point m? a) (-2, 5) b) (-5, 2) c) (5, -2) d) (-2, -5)

Find the midpoint m of z1=(8+5i) and z2=(12+3i)

Can someone check if i did this right since i really want to make sure it’s correct. if you do you so much
