Answer:

x=\frac{14}{5} or 2.8

Step-by-step explanation:

combine like terms 2x-7x = -5x

subtract 12 from both sides to get -2-12 which = -14

-5x = -14

x=\frac{14}{5}

Because
\frac{f(x)}{x-3} = 2x^{2} + 10x - 1
therefore
f(x) = (x-3)(2x² + 10x - 1) + k, where k =  constant.

Because f(3) = 4, therefore k =4.
The polynomial is
f(x) = 2x³ + 10x² - x - 6x² - 30x + 3 + 4
      = 2x³ + 4x² - 31x + 7

Answer:  f(x) = 2x³ + 4x² - 31x + 7
