Question
Find the product. (𝑥 + 9)(𝑥 + 9)
Hint:
The methods used to find the product of binomials are called special products.
Multiplying a number by itself is often called squaring.
For example (x + 3)(x + 3) = (x + 3)2
The correct answer is: 81
(x + 9)(x + 9) = x(x + 9) + 9(x + 9)
= x(x) + x(9) + 9(x) + 9(9)
= x2 + 9x + 9x + 81
= x2 + 18x + 81
Final Answer:
Hence, the simplified form of (𝑥 + 9)(𝑥 + 9) is x2 + 18x + 81
Final Answer:
Hence, the simplified form of (𝑥 + 9)(𝑥 + 9) is x2 + 18x + 81
This question can be easily solved by using the formula
(a + b)2 = a2 + 2ab + b2

Graph the equation 
We can find the tabular values for any points of x and then plot them on the graph. But we usually choose values for which calculating y is easier. This makes plotting the graph simpler. We can also find the values by putting different values of y in the equation to get different values for x. Either way, we need points satisfying the equation to plot its graph.
