The solution of the given equation is +9 and -9.
Step-by-step explanation:
Given,
[tex]g(x) = 7x^{2} =567[/tex]
To find the solution of x.
[tex]7x^{2} = 567[/tex]
or, [tex]x^{2} =\frac{567}{7}[/tex]
or, [tex]x^{2} = 81[/tex]
or, x = ±[tex]\sqrt{81}[/tex] [ square roots has two values so we put ±]
or, x = ±9
