Question

Find the value of a for which the polynomial 3x^3+14x^2+9x+a is divisible by 3x+5

Answer 1

Answer:

a = -10

Step-by-step explanation:

3x + 5 = 0

or, x = -5/3

3*(-125)/27 + 14*25/9 + -45/3 + a = 0

or,  -125/9 + 350/9 - 15 + a = 0

or, 225/9 - 15 + a = 0

or,  25 - 15 + a = 0

or, 10 + a = 0

or, a = -10
