Question

$(1+m) x^{2} -2(1+3m)x+( 1+8m)=0$

Answer 1

well x can be expressed in terms of m using formula
$x= \frac{-b+ \sqrt{b^2-4ac} }{2a}, \frac{-b- \sqrt{b^2-4ac} }{2a}$
$x=\frac{-2(1+3m)+ \sqrt{4(1+3m)^2-4(1+m)(1+8m)} }{2(1+m)}, \\ \frac{-2(1+3m)- \sqrt{4(1+3m)^2-4(1+m)(1+8m)} }{2(1+m)}$
now u can solve it
