Answer

The exact solution of  x is 2.65  for the given equation 3x² + 7 = 28 .

Step-by-step explanation:

The equation given in the question is as follows.

3x² + 7 = 28

Now simplify the above eqaution

3x² = 28 - 7

3x² = 21

[tex]x^{2} = \frac{21}{3}[/tex]

x² = 7

[tex]x = \sqrt{7}[/tex]

[tex]x = \sqrt{7}[/tex]

x = 2.65

Therefore the solution for x is 2.65  for the given equation 3x² + 7 = 28 .
