Question

Use the work shown to find the solutions of the quadratic equation.

x2 – x – StartFraction 3 Over 4 EndFraction = 0

x2 – x = StartFraction 3 Over 4 EndFraction

x2 – x + (StartFraction 1 Over 2 EndFraction) squared = StartFraction 3 Over 4 EndFraction + (StartFraction 1 Over 2 EndFraction) squared

x2 – x + StartFraction 1 Over 4 EndFraction = StartFraction 3 Over 4 EndFraction + StartFraction 1 Over 4 EndFraction

Which is a solution of x2 – x – StartFraction 3 Over 4 EndFraction = 0?

Answer 1

How about just typing it normally, such as
x^2 - x - 3/4 = 0

times 4 ...
4x^2 - 4x - 3 = 0 , it factors nicely
(2x - 3)(2x + 1) = 0
x = 3/2 or x = -1/2

now, re-enter the others and show why you are having difficulties.
