Question

b) f(x) = 5x + x2 - 5x - 1, g(x) = x + 1
(i) f(x) = x3 + 3x² + 3x + 1, g(x) = x + 1​

Answer 1

Answer:

b)-3

i) 0

Step-by-step explanation:

b) x+1=0

×=(-1)

5(-1)+2(-1)-5(-1)-1

-5+(-2)-(-5)-1

-5-2+5-1

-5 and +5 will cancel

-2-1

-3

i)×+1=0

×=-1

(-1)^3+3(-1)^2+3(-1)+1

-1+3+(-3)+1

-1and +1 will cancel

-3,+3will cancel

thus =0,,

Answer 2

Answer:

b) Quotient = 5x^2-4x-1

Remainder = 0

(i) Quotient = x^2+2x+1

Remainder = 0
