How do you long divide #(2x^3+5x^2-36x+27) ÷ ( x-2)#?
1 Answer
Answer:
Explanation:
Polynomial long division like so
Step 1 : Write the numerator in descending order
Step 2 : Start diving. Ask yourself how many time is
Step 3: Multiply the quotient from step 2, to the divisor and subtract form dividend.
Repeat step 2 and 3 until we can't divide any more.
The quotient for polynomial division is
Q(x) = Quotient
R(x) = Remainder
d= divisor
