Find the quotient and the remainder for
answer fast guys
Answers
By division method, we can easily find out the quotient and remainder.
x - 1 ) 3x³ - 2x² + x - 2 ( 3x² + x + 2
3x³ - 3x²
( - ) ( + )
------------------------------------
x² + x
x² - x
( - ) ( + )
------------------------------------
2x - 2
2x - 2
( - ) ( + )
------------------------------------
0
So,
→ Quotient = 3x² + x + 2
→ Remainder = 0
- Quotient = 3x² + x + 2
- Remainder = 0
We know that,
→ Dividend = Divisor × Quotient + Remainder
Here,
→ Dividend = 3x³ - 2x² + x - 2
Divisor × Quotient + Remainder,
= (x - 1)(3x² + x + 2) + 0
= x(3x² + x + 2) - 1(3x² + x + 2)
= 3x³ + x² + 2x - 3x² - x - 2
= 3x³ - 2x² + x - 2
= Dividend.
So, our answer is correct (Verified)
