If a solution 2(2x-1)=5x^2 is expressed in simplest form a + bi form the value of b is

b = 0.4899

Step-by-step explanation:

Given;

2(2x-1)=5x²

4x - 2 = 5x²

5x² - 4x + 2 = 0

this is a quadratic equation with;

a = 5, b = -4 and c = 2

in terms of a + bi, it will be simplified as;

Therefore, b = 0.4899

- 1.613 = -1.6 or -1.61

-1.522 = -1.5 or -1.52

0.587 = 0.6 or 0.59

3.079 = 3.1 or 3.08
