Answer:
The roots of any quadratic equation is given by using: x = [-b +/- sqrt(-b^2 - 4ac)]/2a. Write down the quadratic in the shape of ax^2 + bx + c = zero. If the equation is in the shape y = ax^2 + bx +c, honestly replace the y with zero. that is achieved because the roots of the equation are the values where the y axis is same to 0.
The answer would be x > or equal to 0.
Answer:
It would have to be |4-(-1)| and |-1-4|
Step-by-step explanation:
Because its saying the absolute value of those things, and the distance between them is 5 so the absolute value of 5 is 5 and the absolute value of negative 5 is also 5 meaning that those two are the correct answers
This is how I find the GCF.
I find the prime factors.
63/3 = 21
21/3 = 7
7/7 = 1
81/3 = 27
27/3 = 9
9/3 = 3
3/3 = 1
Then I find the common prime factors:
63: 3 x 3 x 7
81: 3 x 3 x 3 x 3
Then I multiply the common prime factors:
3 x 3 = 9
The GCF for 63 and 81 (number 3) is 9.
I bet you can use this method for all the other GCFs! :)
For this one, find the prime factors like before, and if there aren't any besides one, then it's a prime number.
75/3 = 25
25/5 = 5
5/5 = 1
The prime factorization for 75 is 3 x 5 x 5
(I don't know the answer to 7, 8, 9, 10, 11, 12, 25, or 26, sorry!)
