The solutions of the quadratic equation 0 = -3x² - 4x + 5 are
and 
Step-by-step explanation:
The quadratic formula of the quadratic equation ax² + bx + c = 0, is

To find the solution of the quadratic equation by using quadratic formula
- Find the values of a, b, and c from the quadratic equation
- Substitute these values in the quadratic formula
- Calculate the values of x
∵ -3x² - 4x + 5 = 0
∴ a = -3 , b = -4 and c = 5
- Substitute these values in the quadratic formula
∵ 
∴ 
∴ 
- Simplify by dividing up and down by -2
∴

Answer:
-66.66666667 percent
Step-by-step explanation:
Where: 57 is the old value and 19 is the new value. In this case we have a negative change (decrease) of -66.66666667 percent because the new value is smaller than the old value.
243 + 62 - 28 = n
n = 305 - 28
n = 277
