# Math Help - Solve the equation

1. ## Solve the equation

3^(2x+2)-10(3x)+1=0
This is another hard question ... my teacher want me to get x=0,x=1 .. but i cant seems to get it .

2. ## Re: Solve the equation

Is that "10(3x)" supposed to be 10(3^x)? If so recall that 3^(2x+ 2)= (3^(2x)(3^2)= 9((3^x)^2). So if you let y= 3^x, you get a quadratic equation for y.
