When f(x) = 15x3 – 14x2 – 4x + 10 is divided by (3x + 2), then the remainder is:
-1
1
-2
2
f(x) = 15x3 – 14x2 – 4x + 10 is divided by (3x + 2)
Put 3x + 2 = 0 ,
x = (-\(\frac{2}{3}\)) put the value of x given equation, = 15x3 – 14x2 – 4x + 10, = 15(-\(\frac{2}{3}\))3 - 14((-\(\frac{2}{3}\))2 - 4(-\(\frac{2}{3}\)) +10 = (-\(\frac{40}{9}\))- (\(\frac{56}{9}\)) + (\(\frac{8}{3}\)) + 10 = (\(\frac{114}{9}\)) - (\(\frac{96}{9}\)) = (\(\frac{18}{9}\)) =2
