Idk how people understand algebra help me
1 answer:
To factor by a binomial, I like to use synthetic division (You can use long division but it is more work).
We are actually given a binomial because if -2 is a zero, the binomial is represented by (x- (-2)) or (x+2)
To use synthetic division,
-2 | 1 2 -9 -18
-2 0 18
____________
1 0 -9 0
Therefore, you know the constants of the equation which is equal to
1x^2 +0x -9x +0
x^2-9x
The full equation is equal to (x+2)(x^2-9x)

Answer:
y = -1/2x - 11/2
Step-by-step explanation:
y2 - y1 / x2 - x1
-4 - (-5) / -3 - (-1)
1/ -2
= -1/2
y = -1/2x + b
-5 = -1/2(-1) + b
-5 = 1/2 + b
-11/2 = b
