Question

F(x)=x^3+6x^2+1x+6 give ans

Answer 1

Answer:

x³ + 6x² + x  + 6 =  (x² + 1)(x + 6)

x = -6 or ± i

Step-by-step explanation:

F(x)=x^3+6x^2+1x+6

f(x) = x³ + 6x² + x  + 6

= x²(x + 6) + 1(x + 6)

= (x² + 1)(x + 6)

if f(x) =0

x = -6

or x² = -1

=> x = ±i

x³ + 6x² + x  + 6 =  (x² + 1)(x + 6)
