Question

The given equation is either linear or equivalent to a linear equation. Solve the equation. (If there is no solution, enter NO SOLUTION. If all real numbers are solutions, enter REALS.)
(t − 7)^2 = (t + 7)^2 + 112

Answer 1

t = -4
I'll let Harkirat show solution

Answer 2

using (a-b)^2 = a^2 - 2ab + b^2
and (a+b)^2 = a^2 + 2ab + b^2

t^2 - 14t + 49 = t^2 + 14t + 49 + 112

t^2 - t^2 - 14t - 14t = 49+112-49
-28t = 112
t = 112/-28
t = -4
