Question

what are the coffecient of xsquare​

Answer 1

Answer:

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.
