Answer:
w = 7, 1
Step-by-step explanation:
A perfect square is shown by a²-2ab+b²
If you substitute the question into the formula you get:
w²-(2×4×w)+4²
Simplify and you get:
w²-8w+16=9
Factor:
(w-4)²=9
Square Root both sides:
w-4=±3
w=7, w=1
Answer:
Step-by-step explanation:
We can simplify this equation down until x is isolated.
We can combine the like terms of x.
Add 3 to both sides.
Now we can divide both sides by 5.
.
So x = -5.
