The zeros of a quadratic equation are equal to the x-intercepts of its graph. In other words, you must find the x-value that causes the expression to equal zero. Start by adding 4 to both sides of the equation:
X² - 5x + 4 = 0
Factor the equation:
(x - 1)(x - 4) = 0
Now calculate each piece separately, starting with the first one:
x - 1 = 0
Add 1 to both sides of the equation:
x = 1
We have proven that x = 1. Now calculate the second piece:
x - 4 = 0
Add 4 to both sides of the equation:
x = 4
We have proven that x = 4. Consequently, we have proven that (x = 1) and (x = 4) are the two zeros of this quadratic equation.
I hope this helps!
Answer:
22
Step-by-step explanation:
220 x 15 ÷ 150 = 22
or each gallon gives him 10 miles.
for 220 miles he needs 22 gallons
I can’t read the bottom half of the fraction so I will just assume it’s (a-b) to the power of 3.
So basically you have power of 4 and power of 3. so you can divide the top and bottom by (a-b) to the power of 3 so you would be left with a-b/1 = a-b
Final answer: a-b
