Question

How do you solve `25x^2-24x-9=-7x^2+12x-18`?

Answer 1

Solution : `x=3/4 or x=3/8`

Explanation:

`25 x^2 -24 x -9 = -7x^2 +12x -18`

or `25 x^2 -24 x -9 +7x^2 -12x +18 =0`

or `32x^2 -36 x +9 =0 or 32x^2 -24 x -12x+9 =0`

or `8x(4x-3) -3(4x -3)=0 or (4x-3)(8x-3)=0`

Either `4x-3=0 or x =3/4` or `8x-3=0 or x =3/8`

Solution : `x=3/4 or x=3/8` [Ans]
