Answer:
2(x + 2)(5x-2)
Step-by-step explanation:
Here, we want to factorize the given polynomial
We have this as follows;
10x^2 + 20x - 4x -8
10x(x + 2) - 4(x + 2)
= (10x-4)(x + 2)
We can factor the first side by bringing out two and we will have;
10x-4 = 2(5x-2)
and hence;
2(x + 2)(5x-2)

The division problem for π<span> is 22/7</span><span />
A=length x height. First we want to know the area of the original sheet of paper. 8.5 x 11= 93.5 inches squared. Then we take two squares with side length 2 inches. The area of each of these squares is 2 x 2, or 4 inches. Since there are two, the total area we take away is 8 inches. We subtract 8 inches from 93.5 since we took it away, and the final area of the paper is 85.5 inches^{2}
Hope this helped!
Given, (9x - 4)(9x + 4) = ax² - b
From algebraic identities:
We know, (a + b)(a - b) = a² - b²
Now, 81x² + 36x - 36x - 16 = ax² - b
81x² - 16 = axis² - b
So ax² = 81x²
a = 81
-b = -16
b = 16
Solution
Therefore, the value of a is 81.
