2x^3-3x^2-11x+6 divide by x-3

Step-by-step explanation:

You can do long division, which is very very hard to show with typing on a keyboard. You essentially want to divide the leading coefficient for each term. Ill try my best to explain it.

Do . Write 2x^2 down. Now multiply (x - 3) by it. Then subtract it from the trinomial.

Now do . Write that down next to your 2x^2. Multiply 3x by (x - 3) to get:

Your final step is to do . Write this -2 next to your other two parts

Multiply -2 by (x - 3) to get:

Our remainder is 0 so that means (x - 3) goes into that trinomial exactly:

times

2x² + 3x -2

Step-by-step explanation:

2x³ - 3x² - 11x + 6 : (x - 3)

2x³ - 6x² from (x - 3) * 2x²

—

3x² - 11x + 6

3x² - 9x from (x - 3) * 3x

—

- 2x + 6

- 2x + 6 from (x - 3) * (-2)

—

0

so 2x³ - 3x² - 11x + 6 : (x - 3) = 2x² + 3x -2

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.
