Answer:
x=0 or x=3 or x= -3⅘
Explanation:
Please see attached picture for full solution.
Another way to solve it is to factorise x out from the equation from the beginning. This would leave you with
x(5x² +4x -57x)=0
Then you can factorise the quadratic equation.
x(x -3)(5x +19)= 0
And solve it just like we did above.
x=0 or x-3=0 or 5x+19=0
x=3 or 5x= -19
x= -3⅘
In the picture, I used synthetic division but long division works too!
