can you help me with this
|2x - 3|^2 - 6|2x - 3| + 5=0
I know you are goood with this stuff
Math question here.
let |2x - 3| = y then you have
y^2 - 6y + 5 = 0
(y-5)(y-1)=0
y = 5 or y = 1
or |2x - 3| = 5 or |2x - 3| = 1
So you have |2x - 3| = 5
giving you:
2x - 3 = 5 or -2x + 3 = 5
2x= 4 -2x = 2
x = 2 x = -1
repeat the same steps with |2x - 3| = 1 for 2 more answers.
