Answer:

0 ; -3 ; -8

Explanation:

If we look at the expression we can see that we have two fractions. If one f the denominators is equal to 0, the expression is impossible. So we have to find the values of x that make the denominators equal to 0 and exclude them.

3x^2 + 6x = 0

divide the two members for three

x^2 + 3x = 0

factorize x

x(x +3) = 0

a product is equal to 0 when at least one of the factors is equal to 0, so we have two solutions:

x = 0

x + 3 = 0 ; x= -3

0 and -3 can’t be values of x

x^2 + 11x + 24 = 0

For simplify the work we can factorise the trinomial:

We have to find two numbers whose sum is 11 and whose product is 24

the two numbers are 3 and 8, so we can rewrite the trinomal as:

(x+3)(x+8) = 0

for the consideration made above, we can find

x = -3

x = -8

so the final answer of the question is

0 ; -3 ; -8
