Brian is solving the equation x^2 -3/4 x =15. what value must be added to both sides of the equation to make the left side a perfect-square trinomial?
a. 9/64b.9/16c.3/4d.9/4
To complete the square we get the coefficient of x, divide it by 2 then square it. -3/4 divided by 2 = -3/8 and then squared it equals 9 / 64 answer is a
