All you have to do is carry the 2 over and subtract it from 6 so then you just have 4=4y which will turn into 1=y
Alrighty
remember

means

and

and

for all real values of x
so

means

means

which simplifies to
1=x²+4x-5
minus 1 both sides
0=x²+4x-6
use quadratic formula or complete the square

and

2 solutions
