The answer to this is 62.
Answer:
The solution set of the quadratic function is .
Step-by-step explanation:
Let be a second-order polynomial (quadratic function) is standard form and equalized to zero:
Its roots can be determined by the Quadratic Formula in terms of its polynomial coefficients, which states that:
Given that , and , the roots of the polynomial are, respectively:
The solution set of the quadratic function is .
Difference means to minus
5 1/4 - 2 3/4 =
[since 1/4 cannot minus 3/4, we need to convert one of the 5 wholes into quarters: 5 1/4 = 4 5/4 ]
5 1/4 - 2 3/4
= 4 5/4 - 2 3/4
= 2 2/4
= 2 1/2

Answer:
x = {-0.44, 1.69}
Step-by-step explanation:
Multiply by the denominator to eliminate the fraction.
3 = x(4x -5)
4x^2 -5x -3 = 0 . . . . . subtract 3 and put in standard form
Using the quadratic formula with a=4, b=-5, c=-3, we have the solutions as ...
Solutions rounded to hundredths are ...
x = -0.44
x = 1.69
_____
A graphing calculator can show the x-intercepts easily, so it works well to write the equation in the form
f(x) = 0
3/(4x -5) -x = 0
