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:
a-2=a-2
Step-by-step explanation:
Here it is, you just have to notice that the numerator has common factors alternated. You will then collect the same parentheses and simplify with the denominator.
Hello! So both numbers are negative, so the answer will definitely be positive. All you have to do is multiple straight across. 4 * 7 is 28 and 9 * 9 is 81. That’ll make the fraction 28/81. The product is 28/81.
Answer:
10 feet
Step-by-step explanation:
Find the hypotenuse
a^2 + b^2 = c^2
6^2 + 8^2 =c^2
36+ 64 = c^2
100=c^2
(square root) 100 = 10
c=10
