Answer:
Step-by-step explanation:
Given a general quadratic formula given as ax²bx+c = 0
To generate the general formula to solve the quadratic equation, we can use the completing the square method as shown;
Step 1:
Bringing c to the other side
ax²+bx = -c
Dividing through by coefficient of x² which is 'a' will give:
x²+(b/a)x = -c/a
- Completing the square at the left hand side of the equation by adding the square of half the coefficient x i.e (b/2a)² and adding it to both sides of the equation we have:
x²+(b/a)x+(b/2a)² = -c/a+(b/2a)²
(x+b/2a)² = -c/a+(b/2a)²
(x+b/2a)² = -c/a + b²/4a²
- Taking the square root of both sides
√(x+b/2a)² = ±√-c/a + b²/√4a²
x+b/2a = ±√(-4ac+b²)/√4a²
x+b/2a =±√b²-4ac/2a
- Taking b/2a to the other side
x = -b/2a±√√b²-4ac/2a
Taking the LCM:
x = {-b±√b²-4ac}/2a
This gives the vertex form with how it is used to Solve a quadratic equation.
Answer:
The answer rounded to the nearest percent is 19%.
Step-by-step explanation:
The formula for percent change is this:
((y2 - y1) / y1)*100
Let y1 be the first value (595) and let y2 be the second (708).
((702 - 595) / 595)*100
702 - 595 is 107 and 107/595 is approximately 0.188, multiplied by 100 is 18.8, which is rounded to 19%.
That is our solution.

Look it up, its how it works. 0 can go into 3.2 infinity times.
2/5 * 10 = 2/5 * 10/1 = 20/5 = 4
Answer is 4
Answer:
+-(1,2,4,5,10,20)
Step-by-step explanation:
well if this is factors of -20 (bc 75-95=-20)
then it will be +-(1,2,4,5,10,20)
