One of the factors of 61x3 + 27y3 + 180x²y is
Answers
Answer:
Given : 61x³ + 27y³ + 180x²y
To find : Factorize
Solution:
61x³ + 27y³ + 180 * x² * y
x = - 3y is one of the zero
lets check
61(-3y)³ + 27y³ + 180(-3y)²y
= 27y³ ( - 61 + 1 + 60)
= 27y³ (0)
hence x = - 3y is one of the zero
=> (x + 3y ) is one of the factor
61x² - 3xy + 9y²
x + 3y _| 61x³ + 27y³ + 180x²y |_
61x³ + + 183x²y
