Question

3z2 + 7/4+z2=2 find the positive value​

Answer 1

Answer:

1/4

Step-by-step explanation:

3z2+z2=2-7/4

4z2=1/4

z2=1/16

z=under root (1/16)

z=1/4

Answer 2

$3z^{2} + z^{2} + \frac{7}{4} = 2\\4z^{2} = 2 - \frac{7}{4}\\4z^{2} = \frac{8-7}{4}\\4z^{2} = \frac{1}{4}\\z^{2} = \frac{1}{16}\\z = \sqrt{\frac{1}{16}}\\z = \frac{1}{4}$

Since, you need a positive solution, the answer is 1/4, or else it would be $\frac{+}$1/4.
