Questions
If the lines represented by the equations are parallel to each other, which of the following is correct.
detailed solution
Correct option is C
The conditions that the equation ax2+2hxy+by2+2gx+2fy+c=0 represents pair of h2=ab and af2=bg2parallel lines are and For the equation 2x2+mxy+y2+3x+ly−5=0, the values are a=2,h=m2,b=1,g=32,f=l2Hence, m24=2m2=8m=±22And 2l22=1322l2=92l=±32 Therefore, l=±32,m=±22Talk to our academic expert!
