4. My Favorite Mistake Describe and correct the error in solving for one of the variables in the system:
8x + 2y = -12 and 5x - y = 4
Х
Step 1 5x - y = 4
y = -5x + 4
y=5x-4
Step 2 5x - (5x - 4) = 4
5x -5x + 4 = 4
4 = 4
The mistake made was she
To fix this mistake, Ms. Polo should have

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.

answer is b
