# AS level maths help! watch

1. Hey guys, redoing my first year of AS maths and I'm abit rusty on a few things. I'm currently stuck on a question that is part of my homework wondering if any of you could give me a hand? The question is
show that e equation : 4x^(2x+1) +2=6*4^x
can be written as 2y^2 -3y+1=0 When y = 4^x

Any help is much appreciated
