Just one question? I can solve it pm me. How do I show u the picture?

x=0
x=4
No charge

mathway.com

let me know if you need further explanation

This is wrong, answer is 0 and 4. Try subbing back your answers and you won't get it. Finall step is wrong.

X square minus 4x =0
x (x-4)=0

Hence x is 0 or 4.

5fg to someone who gives me a recent real life experience where they had to use these calculations in their daily lives

I used physics to find out how fast I can theoretically go around a curve in my car

Lol just cuz you suck at math doesn't mean it isn't used by almost everyone that make meaningful improvements on people's lives around the world. But keep telling yourself that it's okay that you're stupid
