Step-by-step explanation:
<u>Given</u>
<u>Divide by the following:</u>
<u>(a) 3x² + 2x + 1</u>
- 6x³ + 4x² - x + 5 =
- 2x(3x²) + 2x(2x) + 2x - 3x + 5 =
- 2x(3x² + 2x + 1) + (-3x + 5)
Quotient = 2x, remainder = -3x + 5
<u>(b) x³ - 3x + 2</u>
- 6x³ + 4x² - x + 5 =
- 6(x³) - 6(3x) + 6(2) + 4x² + 22x - 7
- 6( x³ - 3x + 2) + (4x² + 22x - 7)
Quotient = 6, remainder = 4x² + 22x - 7
<u>(c) 6x² + x - 2</u>
- 6x³ + 4x² - x + 5 =
- x(6x²) + x(x) - x(2) + 3x² + x + 5 =
- x(6x² + x - 2) + (3x² + x + 5)
Quotient = x, remainder = 3x² + x + 5
=
( x - 4 )² / ( x + 3 ) ( x + 1 ), restrictions: x ≠ - 3, x ≠ - 1;

Answer:
I say its number 2
Step-by-step explanation:
Answer:
(X,Y)(18,12)
Step-by-step explanation:
x + y = 30
2x + 4y = 84
___________
2x+2y=60
2x+4y=84
_________
-2y=-24/-2y
y=12
2x+4(12)=84
2x+48=84
2x=84-48
2x/2=36/2
X=18
