in quadratic equations how do i solve for fractions
Accepted Solution
A:
Answer:Just Multiply both sides by LCM of the denominators of the fractions. It works for all equations.Step-by-step explanation:The best way to solve a quadratic equation that contains a fraction. An example is 1/2x^2 - 2x = 3/2.
I multiply both sides by a number that gets rid of the denominators of all the fractions. E.g.,
Multiply your example by 2 on both sides:
x^2 – 4x = 3
x^2 – 4x – 3 = 0
Using Quadratic Formula:
x = (4 ± √(16–4(1)(–3)))/(2(1))
x = 2 ± √(4–(1)(–3))
x = 2 ± √(7)
