Use synthetic division to divide f(x) by x-c then write f(x) in the form f(x) = (x - c)q(x) +r.
f(x) = x3 - 15x2 - 5x + 8; -3
f(x) =

  f(x) = (x +3)(x^2 -18x +49) -139

Step-by-step explanation:

The synthetic division tableau is attached. The coefficients of the quotient are ...

  1, -18, 49

and the remainder is -139.

So, in the desired form, f(x) can be written as ...

  f(x) = (x +3)(x^2 -18x +49) -139

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
