The solution of the equation 4x² - 20x + 9 = 0 will be 0.5 and 4.5.
<h3>What is a quadratic equation?</h3>
The quadratic equation is given as ax² + bx + c = 0. Then the degree of the equation will be 2. Then we have
The equation is given below.
x² - 5x = -9/4
Then the equation can be written as
4x² - 20x + 9 = 0
Then the factor of the equation will be
4x² - 20x + 9 = 0
4x² - 18x - 2x + 9 = 0
2x(2x - 9) -1 (2x - 9) = 0
(2x - 1)(2x - 9) = 0
Then the solution of the equation 4x² - 20x + 9 = 0 will be
x = 0.5, 4.5

hope this is right!
please let me know
4/7 of the children in the pool are girls
3/7 of the children in the pool are boys
4/7:3/7
4:3 is the ratio of girls to boys
