Question

7tsquared-4t=3tsquared-1

Answer 1

subtract 3t^2 - 1 from both sides, and you get 4t^2 - 4t + 1 = 0. Then factor. Can you do that?

Answer 2

subtract 3t^2 from each side, add one to each side.

4t^2-4t+1=0
(2t-1)^2=0
take the sqrt for each side, and solve for t.

Answer 3

7t^2 - 4t= 3t^2 - 1
4t^2 -4t +1 = 0
(2t - 1)^2 = 0
2t - 1 = 0
t = 1/2 is the only solution
