The midpoint of the diagonal of a rectangle formed by x^2+5 x-6=0 and y^2-8 y-20=0 is

Options

  1. A( 5 2 , 4 )
  2. B( -5 2 ,-6 )
  3. C( -5 2 , 4 )
  4. D( 5 2 ,-6 )

Correct answer

C. ( -5 2 , 4 )

Step-by-step solution

aligned & x ^2+5 x -6=0 x ^2+6 x - x -6=0 & ( x -1)( x +6)=0 x ₁, x ₂=1,-6 & y ^2-8 y -20=0 y ^2-10 y +2 y -20=0 & ( y -10)( y +2)=0 y ₁, y ₂=-2,10 aligned Midpoint of the diagonal = ( x₁+x₂ 2 , y₁+y₂ 2 )= ( -5 2 , 4 )
