$5,625 is the correct answer for this because of the additional
Answer:
x =0 and x = 4
Step-by-step explanation:
It is a quadratic function and hence will have two roots. It cuts graph at 2 points( x - axis ). Hence has two roots.
Answer:
yes 2/3 is greater than 5/7
Step-by-step explanation:
beacuse when it says 2/3 i mean 2 out of 3
and when it says 5/7 it mean the same thing
so i kinda use this method i dont know if u will like it tho
so I just do this ......
3-2= 1
5-7 = 2
which number is leastest thats the greater one.
i hope it help :)
The reason why we used plus or minus when taking the square root is because; The square root of terms separated by addition and subtraction cannot be calculated individually.
<h3>How to use the quadratic formula?</h3>
The general formula for a quadratic equation is;
ax² + bx + c = 0
Now, the steps to derive quadratic formula to find the roots of this equation are as follows;
Step 1; Divide both sides of the equation by a to get;
x² + (b/a)x + c/a = 0
Step 2; Transpose the quantity c/a to the right side of the equation to get; x² + (b/a)x = -c/a
Step 3; Complete the square by adding b²/4a² to both sides of the equation to get; x² + (b/a)x + b²/4a² = -c/a + b²/4a²
Step 4; Factor the left side and combine the right side to get;
(x + (b/2a))² = (b² - 4ac)/(4a²)
Step 5: Extract the square-root of both sides of the equation to get;
x + (b/2a) = ±(√(b² - 4ac))/2a
The reason why we used plus or minus when taking the square root is because The square root of terms separated by addition and subtraction cannot be calculated individually.
