solve for x: 2x^2+5x+6= x^2+5x+6

[dayton1]

I have to solve for x for this equation......but I can't seem to do it right!

2x^2+5x+6= x^2+5x+6

It seems that no matter what you do you eliminate the x and end up with only the x^2 numbers.....any help?

Don't worry. You're on the right track. Keep going with what you have:
2x² = x²
2x² - x² = 0

...

Can you see the end result is?

ok so then I have x(2x-x)=0 , Right???? Then what! arrghh :x .

\(\displaystyle \L 2x^2+5x+6= x^2+5x+6\)

Subtract all right hand side terms from both sides

\(\displaystyle \L 2x^2-x^2+5x-5x+6-6 = 0\)

\(\displaystyle \L x^2 = 0\)
