$\fcolorbox{blue}{lavendarblush}{Coefficient of x Squared}$

x = 3 or x = -1/3.

Problem

#1. Solve for x if 2x2 + x - 15 = 0.

Solution

#1. If we multiply the entire equation by 2, we get: 4x2 + 2x - 30 = 0. Thus, to complete the square, the constant term must be 1/4. Since it's -30 (or -120/4), we need to add 121/4 to both sides: 4x2 + 2x - 30 + 121/4 = 121/4. 4x2 + 2x + 1/4 = 121/4.
