Question

If 49x² − b = (7x² −1/2) (7x² +1/2) then find the value of b_______

Answer fast

Answer 1

hope it helps you dude

Answer 2

49$x^{2}$ -b =( 7x² + $\frac{1}{2}$)(7x² + $\frac{1}{2}$)
49x²-b=(7x²)²- ($\frac{1}{2}$)²
49x²-b= 49$x^{4}$ -$\frac{1}{4}$
-b=49$x^{4}$  - $\frac{1}{4}$ - 49x²
B= - 49$x^{4}$ + $\frac{1}{4}$ + 49x²
i hope it helps u!!!!!
