This is equation of degree 2 in t +3. The roots are 2 numbers whose sum is 12 and whose product is 35, that is, 5 and 7.

So, the roots of your equation are the solution of t +3 = 5 and t +3 = 7, that is 2 and 4.

Of course , you could develop your equation to get an equation in t, but this would require much more algebraic work

There's more than one way to do this one. Here's one way,

Let x = t + 3. Then we are looking for the solutions of x^2 - 12x + 35 = 0.

This factors as (x - 7)(x - 5) = 0. So the solutions of the equation are x = 5, x = 7.

Since x = t + 3, this means that t = 2, t = 4 are solutions to the original equation.

t+2 = z

Fin z and then find t
