Find the equation of the plane through the points , \boldsymbol{B}(\mathbf{3}, \

Find the equation of the plane through the points \( \boldsymbol{A}(\mathbf{2}, \mathbf{2}-\mathbf{1}), \boldsymbol{B}(\mathbf{3}, \mathbf{4}, \mathbf{2}) \) and \( \boldsymbol{C}(\boldsymbol{7}, \boldsymbol{0}, \boldsymbol{6}) \)

  • A. \( 5 x+2 y-3 z=17 \)
  • B. \( 5 x+2 y+3 z=17 \)
  • C. \( 5 x+y-3 z=7 \)
  • D. \( 5 x+y+3 z=7 \)

Step-by-step solution

Vectors AB = (1,2,3) and AC = (5,-2,7). Normal vector n = AB × AC = (20,8,-12) = 4(5,2,-3). Using point A, plane equation: 5(x-2)+2(y-2)-3(z+1)=0 simplifies to 5x+2y-3z=17.
