There are tow answers one is an improper fraction and the other is a simplified fraction. Answer 11/8. Answer 1 and 3/8.
Expand (x+2)^2: x^2 + 4x + 4 : remember that (a+b)^2 = a^2 + 2ab + b^2
So: x^2 + 4x + 4 - x^2 = 60
Step-by-step explanation:
2/8=3/x+2
We move all terms to the left:
2/8-(3/x+2)=0
Domain of the equation: x+2)!=0
x∈R
We get rid of parentheses
-3/x-2+2/8=0
We calculate fractions
There is no solution for this equation
