Question

I F 49x ²b = (7x +1/2)(7x-1/2)then Find the value b.​

Answer 1

Answer:

0

Step-by-step explanation:

Apply Only the Outside and Inside Method of the Foil Method.

$7 \times - \frac{1}{2} = - 3.5x$

$\frac{1}{2} \times 7x = 3.5x$

Add them together

$- 3.5x + 3.5x = 0$

So our b value is 0.
