First you want to get the equation to equal zero before you use the quadratic formula so the new equation is : [latex]2 x^{2} -5x-25=0[/latex] The quadratic formula is: [latex](-b+ sqrt{b^2-4ac})/2a [/latex] [latex](-b-sqrt{b^2-4ac})/2a [/latex] the difference between those equations is that their is a + and - sign after the first b in the equation The letters that correspond with the numbers are : a=2 b=-5 c=-25 so you plug those into your quadratic formulas and get: x=5 x=-5/2
