Hi im having problems with these questions:
Q1. Find the equation of the plane which contains points (2,-1,4), (3,2,-1) and perpendicular/orthogonal to the plane x + y + 2z = 3.
Q2. Find the equation of the plane containing the point (3,-1,-5) and perpendicular/orthogonal to the planes 3x - 2y + 2z = -7 and 5x - 4y + 3z = -1.
Explanation, answers and steps would be appreciated,
