Prove that r1 and r2 intersect at (1,1,3).

Let r1 and r2 be defined as:

r1(t)=t^2i+tj+3t^3k

r2(t)=(t−1)i+(1/4)t^2j+(5−t)k

2. Relevant equations

Intersection is derived from r1=r2.

3. The attempt at a solution

I only formally get to this point and then start messing up. It gets messy and I know i'm not doing the right thing.

r1=r2 --> t^2i+tj+3t^3k = (t−1)i+(1/4)t^2j+(5−t)k
