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.

Step-by-step explanation:
Let the integers be x and 2x
ATQ,
- x.2x =50
- 2x^2=50
- x^2=50/2
- x=25^(1/2)
- x=5
Steve didn't put the parenthesis when he went to the second part of the equation, instead of putting the parenthesis he skipped them and keep going along with the equation.
