Dividing Polynomials
What is the first step to solving? (Hint: look at divisor)
Set divisor equal to 0 and solve for x
If the last number is 0 what does that mean about the divisor?
The divisor is a factor of the polynomial
When dividing by x+5 using synthetic division what number should be placed outside the box?
-5
What happens if there is a missing coefficient? What must you do?
Use 0 as a placeholder for said coefficient
What do all numbers under the L represent after solving?
The quotient
What does the last number represent if you were to find f(94)?
The value of y when x is 94
(x3-4x2+2x+7)/(x-3) Is x-3 a factor?
No
f(x)=x2-4x+3 find f(1)
0
(x4-3x2+7x-10)(x+2)
What is the Quotient/Remainder/Y when x=-2
Quotient: x3-2x2+x+5 -20/x+2
/
Remainder: -20
/
Y when x=-2: -20
f(x)=2x4+5x2-8 find f(3)
