Answer:
Step-by-step explanation:
1. Find two numbers that add to make the coefficient of x (in this case, -5) and that multiply to make the constant term multiplied by the coefficient of x^2 (in this case, -2 x 3 = -6)
Two numbers that work are -6 and +1
-6 x +1 = -6
-6 + -1 = -5
2. Split the middle term into the two numbers that you found.
3x^2 -6x +x -2 = 0
I've put the -6 on the left side because in our next step, when we factorise, it will be easier than having the numbers the other way around.
3. Factorise the left side by taking out common factors from each pair. The pairs I'm talking about here are '3x^2 and -6x', and 'x and -2'
3x (x-2) +1 (x-2) = 0
4. You now have two numbers both being multiplied by the term x-2. We can rearrange this equation to give us two brackets being multiplied by each other.
(3x + 1) (x-2) = 0
5. According to the Null Factor Law, if two terms are multiplied together and the result is 0, then one of those terms must be 0. Make both terms equal to 0 and solve each for x.
3x + 1 = 0 x-2 = 0
3x = -1 x = 2
x = -1/3
6. The solutions to this equation are x = 2 and x = -1/3
Peter hits 2 times the difference of the number of home runs. So Alice hits 6 home runs.
Altogether they hit 18 home runs.
2*p(18 -6)
so to figure how many home runs there r figure out the equation above.
Alice - 6
Peter - ?
(sorry if it don't help much but that what I can figure out)
Answer:
Step-by-step explanation:
(x-6)² + y²-8y = 0
Put the equation into center-radius form.
complete the square
coefficient of the y term: -8
divide it in half: -4
square it: (-4)² = 4²
add 4² to both sides to complete the square and keep the equation balanced:
(x-6)² + (y²-8y+4²) = 4²
(x-6)² + ( y-4)² = 4²
center (6,4)
radius 4
