write the quadratic equations in `ax^(2)+bx+c=0` form and find the values of a,b,c.
`"(i) " m(m-7)=0 " (ii) " (x^(2)-7)/x=7`
`"(iii) " x-6/x=5 " (iv) " (x+5)(x-11)`

Answer

(i) `m^(2)-7m+0=0` and a=1, b=-7, c=0
(ii) `x^(2)-7x-7` and a=1, b=-7, c=-7
(iii) `x^(2)-5x-6=0` and a=1, b=-5, c=-6
(iv) `x^(2)-6x-55=0` and a=1, b=-6, c=-55
