Answer 1

Answer:

1/4

Step-by-step explanation:

From the given equation we get,

\begin{gathered}49x^{2} - b = (7x + \frac{1}{2})(7x - \frac{1}{2}) \\ \\ 49 {x}^{2} - b = {(7x)}^{2} - ( { \frac{1}{2} )}^{2} \\ 49 {x}^{2} - b = 49 {x}^{2} - \frac{1}{4} \\ - b = - \frac{1}{4} \\ b = \frac{1}{4} \end{gathered}
