Sent a picture of the solution to the problem (s).
So first what you are going to do is divide synthetically your root aka factor into your given equation. Then you are going to kind of guess ands check to find the other factor by synthetically dividing what you have left which should be
x^2 +2x +1 by -5, 5 (to make sure there is no multiplicity), 1, and -1 until you get zero in your remainder spot. The number you used to divide will be your other root.
(x - 3)(x - 5) = 35
Simplify the left side.
x² - 5x - 3x + 15 = 35
Add your like terms.
x² + (-5x - 3x) + 15 = 35
Simplify.
x² - 8x + 15= 35
Simplify.
x² - 8x + 15 = 35
Subtract 35 from both sides of the equation.
x² - 8x + 15 - 35 = 35 - 35
Simplify.
x² - 8x - 20 = 0
Then, you simply factor out the left side of our equation.
(x + 2)(x - 10) = 0
Set it so that each factor equals zero. This basically just means that you take each equation inside the parenthesis and you make them equal zero.
x + 2 = 0 AND x - 10 = 0
x + 2 = 0
Subtract 2 from both sides.
x = -2
x - 10 = 0
Add 10 to both sides.
x = 10
So, x = -2 AND x = 10
So, you got your answer wrong.
~Hope I helped!~
Answer:
1/3
Step-by-step explanation:
The total number of marbles is
4red+ 3 green + 5 blue = 12 marbles
P(red) = number of red/ total
= 4/12
=1/3
The correct answers to this include B,D,E
