**LeAnn**, Thursday, November 19, 2009 at 12:04amI'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

**drwls**, Thursday, November 19, 2009 at 12:16amRewrite 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.
