The solution to the quadratic equation 2x² - 4x - 3 = 0 is given as x = 1 ± √5/2
An equation is an expression that shows the relationship between two or more numbers and variables.
Given the quadratic equation:
2x² - 4x - 3 = 0
Using completing the square, add 3 to both sides:
2x² - 4x - 3 + 3 = 0 + 3
2x² - 4x = 3
Divide through by the coefficient of x²:
x² - 2x = 3/2
Add to both sides the square of half the coeficient of x:
x² - 2x + 1 = 3/2 + 1
(x - 1)² = 5/2
x = 1 ± √5/2
The solution to the quadratic equation 2x² - 4x - 3 = 0 is given as x = 1 ± √5/2
