Algebra 2 URGENT
posted by Trisan .
Solve by using the quadratic formula. Please Show All Work!
4x(x+3)=15

I'm not quite sure how this one would be done. I tried to figure it out for you. However this is the answer I'm getting.
4x(x+3)=15
4x(1x)+12x=15
4 times 1 is 4+12=16
Sorry, I tried to help you but I'm having issues in Algebra too and I have a few on here I haven't got help with yet 
Rewrite it in standard format for quadratic equations, ax^2 + bx + c = 0.
In your case,
4x^2 +12x 15 = 0
so a = 4, b = 12 and c = 15.
Now apply the quadratic equation to get the two solutions. If you don't know what that is, it's time you learned it. It should be easy to find in your textbook or online.
