y=(3/2)x  s=(√(1+(9/4)))=((√(13))/2)  p=(1/2)+(s/( (√2)))cos θ=(1/2)+((√(13))/2)×(1/( (√2)))×(3/( (√(13))))  q=(3/4)−(s/( (√2)))sin θ=(3/4)−((√(13))/2)×(1/( (√2)))×(2/( (√(13))))  tan θ=(2/3)  p=((3(√2)+2)/4)       q=((3−2(√2))/4)  x^2 =(((3(√2)+2)/4)−1)^2 +(((3−2(√2))/4))^2     =((18+4−12(√2)+9+8−12(√2))/(16))    =((39−24(√2))/(16))  x=((√(39−24(√2)))/4)
