How do i do this type of question???
factorise x^3+5x^2+2x-8=0
hence,solve 8y^3+20y^2+4y-8=0
Thanks

When a teacher sets this type of question without giving a clue for the students, it will be difficult to get the relationship between the x and y for the students.
TS has not given an obvious relationship between x and y for the question
However, with the help of the calculator Casio Fx 95SG Plus, we can find the relationship between x and y.
Use the equation mode to calculate the x answers and the y answers and form the relationship between x and y.
Next, use this relationship to solve for the y answers.
