I am definitely not the best at math. Can someone please help me answer these Trinomial Factoring problems?
1. y^(2x)-y^x-20
2. a^2-5a-6
3. 10b^2+17b+3
4. 3x^2+2xy-y^2
5. x^2-2x-24

thank you so much if you can help

put
$$y^x=t,squaring $$
$$\left( y^x \right)^2=t^2,$$
$$y ^{2x}=t^2$$
$$t^2-t-20$$
make factors
