Can someone tell me what i'm doing wrong? i think i know how to do quadratic formula, and i know all the steps, but the last step where you solve after everything is in it's place really confuses me. i put some pictures of what i did and what the question was.

*most answer will be the brainliest! **

Okay, so first you set equal to 0:


Next simplify the equation so that the leading coefficient is positive:


Looking at the quadratic equation you can't easily simplify it, so plug it into the quadratic equation and simplify:


I noticed a couple mistakes in your work, so if you want me to I can explain them in the comments section :)

The pic above shows answer

Nvm it tho now
