Solve the equation for x by finding a , b , and c of the quadratic then applying the quadratic formula
Exact form:
x = 5 ± √ 17
4
Decimal:
x = 2.28077640 … , 0.21922359
sorry idk how to put a fraction in
Answer:
The exact solution is (5 ± √17) / 4.
Step-by-step explanation:
2x^2 = 5x-1
2x^2 - 5x + 1 = 0
then,
a = 2, b = -5, c = 1
Now, by using quadratic formula,
(-b±√(b²-4ac)) / (2a)
(5 ± √(-5)^2 - 4(2)(1)) / 2×(2)
(5 ± √17) / 4.
