Help! problem:<br>5-x=11+x
snow_tiger [21]
The answer is x=-3

5-x=11+x
-11  -11             First subtract 11
-6-x=x          
+x  +x                Now add x to both sides
-6=2x 
~2 ~2                 Finally divide by 2
-3=x                   Your answer is x=-3

Find all roots: x^3-7x^2-12x = 0
Pepsi [2]

Answer:

The roots are  0, 3 and 4.

Step-by-step explanation:

x^3-7x^2-12x = 0   Take out x:

x(x^2 - 7x - 12) = 0  Factor the expression in the brackets:

x(x - 3)(x - 4) = 0

x = 0 or x - 3 = 0 or x - 4 = 0, so

The roots are  0, 3 and 4.
