Question

Simplify and state restrictions.

Answer 1

We have the equation

`(4*a^2*b^2*c)/(-3*a*b) + (8c^2)/(15)`

First, we want the same denominator in both equations, so we can multiply in the left by 5, and in the right bt -ab, and now we have:

`(20*a^2*b^2*c)/(-15*a*b) + (-ab8c^2)/(-15ab) = (-20*a^2*b^2*c +8*a*b*c^2)/(15*a*b)`

Now we have all in the same rational.

The only restriction in this type of equation is that the denominator never can be zero.

so 15*a*b = 0 is a restriction:

This means that a can not be zero, and b can not be zero.
