Answer:

(x - 3) is a factor of P(x)

Step-by-step explanation:

if (x - 3) is a factor of P(x) then P(3) = 0

P(3) = 2(3)³ + 5(3)² - 28(3) - 15

      = 2(27) + 5(9) - 84 - 15

      = 54 + 45 - 99

      = 99 - 99

      = 0

since P(3) = 0 then (x - 3) is a factor of P(x)

How do u turn y-4=5/3(x+3) into standard form
BARSIC [14]

well, bearing in mind that standard form for a linear equation means

• all coefficients must be integers, no fractions

• only the constant on the right-hand-side

• all variables on the left-hand-side, sorted

• "x" must not have a negative coefficient

so hmmm we have a fraction.... so let's multiply both sides by the LCD of all fractions to do away with denominators, hmmm say the LCD will just be 3, so we'll multiply both sides by that

\bf y-4=\cfrac{5}{3}(x+3)\implies y-4=\cfrac{5(x+3)}{3}\implies \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{3}}{3(y-4)=3\left( \cfrac{5(x+3)}{3} \right)} \\\\\\ 3y-12=5(x+3)\implies 3y-12=5x+15\implies 3y=5x+27 \\\\\\ -5x+3y=27\implies 5x-3y=-27
