If 9x2-b=3x+12 3x-12, then the value of b is(a) 0(b) 12(c) 14(d) 12

1.	If 9x2-b=3x+12 3x-12, then the value of b is(a) 0(b) 12(c) 14(d) 12
Answer» ^{If $9 x^{2} - b = (3 x + \frac{1}{2}) (3 x - \frac{1}{2})$ ,}then the value of b is (a) 0 (b) $\frac{1}{\sqrt{2}}$ (c) $\frac{1}{4}$ (d) $\frac{1}{2}$
