    you're using two kinds of 'x' terms one is for the variable and the other is for multiplication is that correct?

    You'll have to use the quadratic formula because when you expand out the right side, you'll get a quadratic

    is there any faster method other than quadratic? because it's expected for me to solve this in like... a minute hahaha

    no you can't avoid solving it without using a graphing calculator or the quadratic formula because you have a quadratic on the right side
