Question

when x³+3x²+1 is divided by x+1 then reminder is? ​

Answer 1

when x³+3x²+1 is divided by x+1 then reminder is?

• x³+3x²+1

$\longrightarrow$x + 1 = 0

$\longrightarrow$x = - 1

• Put x = - 1

$\dashrightarrow$( -1)³ + 3 ( -1)² + 1

$\dashrightarrow$ - 1 + 3 + 1

$\dashrightarrow$ 3

Answer 2

when x³+3x²+1 is divided by x+1 then reminder is?

x³+3x²+1

⟶ x + 1 = 0

⟶ x = - 1

Put x = - 1

⇢ ( -1)³ + 3 ( -1)² +

⇢ - 1 + 3 + 1

⇢ 3
