[@nopzy5975]

ok sir A rational equation is an equation containing at least one rational expression. Rational expressions typically contain a variable in the denominator. For this reason, we will take care to ensure that the denominator is not 0 by making note of restrictions and checking our solutions.

Dahil ang aim lang natin is maequate natin sa zero ang buong equation at mapapunta natin sa kanyang standard form. So kahit sa kaliwa or kanan mo papuntahin ang lahat ng terms, basta maequate mo sya sa zero, tama ang magiging sagot mo. 😊 Sana nakatulong ang sagot ko sayo. 😊
