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
Answer:
Step-by-step explanation:
Hello,
let's note k a real, we can write the polynomial as
and we know that f(0)=216 so
So the solution is
hope this helps
40% of 280 is 112 so to increase by 25% it must increase by 28
Answer:
This is false.
Step-by-step explanation:
The easiest thing to do is notice that 8 goes into 16 whilst 9 doesn't so that shows 9/16 would not be the unit rate.
