(3x2 - 8x - 3) / 2x2 - 6x == (3x + 1)(x - 3) / 2x2 - 6x == (3x + 1)(x - 3) / 2x(x-3) == 3x+1 / 2x
(5-x)/2=2x-7 5-x=4x-14 5=5x-14 19=5x x=19/5
First we should find the gradient of the line perpendicular to PQ by rearranging the equation.5x+3y=113y=11-5xy=11/5 -5/3xy= -5/3x + 11gradient is -5/3.We know that the gradients of perpendicular lines mu...
