Answer:
The value of t is 7 or -7.
Step-by-step explanation:
Consider the provided equation.
[tex]t^2 - 49 =0[/tex]
It is given that first we need to writing the equation in the form [tex]ax^2 = c[/tex]
The write the provided equation in the form [tex]ax^2 = c[/tex] add 49 to the both side.
[tex]t^2 - 49+49 =49[/tex]
[tex]t^2=49[/tex]
[tex]t=\pm\sqrt{49}[/tex]
[tex]t=\pm7[/tex]
[tex]t=7\ or\ t=-7[/tex]
Hence, the value of t is 7 or -7.
