Question

The equation 25x2−9y2=225 can be written in standard form by

Answer 1

Given equation:

`25x^2\text{ - }9y^2\text{ = 225}`

To write in standard form, we divide both sides by 225:

`\begin{gathered} (25x^2)/(225)\text{ - }(9y^2)/(225)\text{ = }(225)/(225) \\ \frac{x^2}{9\text{ }}\text{ -}(y^2)/(25)\text{ = 1} \end{gathered}`

Hence, to write the equation in standard form, we divide both sides by 225
