Multiply 55 by 4!
2
55
x 4

five times 4 is 20, so put 0 then regroup the 2. Then, 5 times 4 again, but add two!
Answer:
3
Step-by-step explanation:
Answer:
what i am supposed to answer
Step-by-step explanation:
First of all Horner
First we try with -3
1. 2. -5. -6.
-3. 3. 6
1. -1. -2. 0
To verify: -3^3+2*-3^2+15-6=0
Now we have this equation
(X+3)*(x^2 - x -2)=0
I dont know If you know sum and product but that is the easiest way so sum= 1 product = 2 so 2 and -1 are the answers.
You can do this too by this way : b^2-4ac= D
X= (-b(+or-)d^1/2)/2a
So all the zeros
2, -1 and -3
If you want more explanation, send me a comment x
Its 0 because the slope would be one if it was a positive line and itd go up and across one unitl and it is undefined if it is parallel to the y axis
