7 1/6 + 5 2/9= tolong dengan penjelasan nya

(x+4)²= (x+4)×(x+4)
Use the FOIL method to simplify
F=First (multiply the first number of each expression) O=Outside (multiply the outside edges of each expression) I= Inside (multiply the inside edges of each expression) L= Last (multiply the last number of each expression)
x times x= x² x times 4= 4x 4 times x= 4x 4 times 4= 16
Add them together, we have: x²+4x+4x+16 We can simplify this by adding like terms 4x+4x=8x
Final expression= x² + 8x + 16

The **quadratic **expression (x+4)² = x² + 8x + 16.
The given **expression **is,
(x+4)²
The expression (x+4)² represents a mathematical operation called " squaring ."
To expand it, we need to **multiply **the expression by itself.
So, (x+4)² becomes (x+4) * (x+4).
When we **multiply **these terms, we apply the **distributive **property and **combine **like terms.
After simplifying , we get x² + 8x + 16.
Or we can directly use the identity ,
(a+b)² = a² + b² + 2ab
Here a = x and b = 4
(x+4)² = x² + 4² + 8x
Hence,
(x+4)² = x² + 8x + 16

To expand ( x + 4 ) 2 , multiply it by itself, resulting in x 2 + 8 x + 16 . This can also be verified using the binomial square formula. Both methods yield the same simplified expression.
