We first factor this quadratic. We want factors of c, -12, that sum to b, -1; -4(3) = -12 and -4+3 = -1, so those are the two we will use:
y=(x-4)(x+3)
The zero product property tells us that in order to get a product of zero, one of the factors must be zero. This means either x-4=0 or x+3=0. We solve both of these equations to find the roots, or x-intercepts:
x-4=0
x-4+4=0+4
x=4
x+3=0
x+3-3=0-3
x=-3
I just learned about it. Simple!
6x=5x+7
Subtract 5x from both sides.
-5x -5x
You end up with
1x=7 or x=7
Answer:
each friend will get 22
Step-by-step explanation:
so you have 176 you divide that by half and you get 88 so then you divide the other 88 by 4 and you get 22 so Reggie kept 88 and all 4 friends each get 22
