Explanation:
it depends on how you interpret what's written. The way I initially interpreted it*, I was able to use the quadratic formula to find :
![x=(1)/(4)-i(√(455))/(20),\:x=(1)/(4)+i(√(455))/(20)](https://img.qammunity.org/2023/formulas/mathematics/high-school/40zrpjt3hjhi082mfhwmm582km7o1hrzsd.png)
*I interpreted it as:
![x\left(x+3\right)-2\left(-5x+1\right)x=x^2-3\left(4-2x\right)](https://img.qammunity.org/2023/formulas/mathematics/high-school/vv7q99203v3lts6z5lpeuxax8xebv9g8qr.png)
but I don't want to say that this is your correct answer, because there are multiple interpretations (like a lot of interpretations)
{this is mostly in response to other answers}
