Solve for h in h+6/5=2

Using the completing-the-square method, find the vertex of the function f(x) = 2x2 − 8x + 6 and indicate whether it is a minimum or a maximum and at what point. maximum at (2, –2) minimum at (2, –2) maximum at (2, 6) minimum at (2, 6)

When are two distinct non vertical lines parallel

What number should be added to both sides of the equation to complete this square? x^2-10x=7
