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 .
