Actually Welcome to the Concept of the Quadratic Equations,

Here, we just use the Quadratic formula to get the roots, that is values of X, since it is an degree 2 variable, so it will have Pair of roots,

x = -b +- underoot b^2-4ac/2a

Hence, answer is +- √7

Given :-

[tex] \bullet \: 3 {x}^{2} + 7 = 28[/tex]

To Find :-

  • Solution of x.

Solution :-

[tex] \longrightarrow3 {x}^{2} + 7 = 28[/tex]

[tex] \longrightarrow3 {x}^{2} = 28 - 7[/tex]

[tex] \longrightarrow3 {x}^{2} = 21[/tex]

[tex] \longrightarrow{x}^{2} = 7[/tex]

[tex] \longrightarrow \bf x = \pm\sqrt{7}[/tex]
