Question

Is x + 3 is a factor of x³ - 5x² + 2x -9

Answer 1

Answer:

No x+3 is not a factor of x^3 - 5x^2 + 2x - 9

Since remainder -87 is coming instead of 0

Answer 2

Step-by-step explanation:

Let, g[x] = x+3

so, x = -3

given:

p[x] = x^3 -5x^2 +2x -9

so, R[-3] = 3^3 -5x[-3]^2+ 2x[-3]-9

= 27 - 45 - 6 -9

= -33

because, x is not = 0

therefore, x+3 is not a factor of x^3-5x^2 +2x -9.
