Answer:
x = √(10) - 2, -√(10) - 2
Step-by-step explanation:
x² + 4x + 4 = 10
factor:
(x + 2)² = 10
take square root of both sides:
x + 2 = ±√(10)
split into 2 equations:
x + 2 = √(10) x + 2 = -√(10)
solve both equations and collect solutions:
x = √(10) - 2, -√(10) - 2
2 is the same as 8/4. you then add 3/4 to 8/4 by adding together the top numbers, or numerators.
3+8=11.
the answer is 11/4. Hope this helps!
