Chelsea, points to take note :
Q2
The degree of the remainder is smaller than the degree of the divisor by at least 1.
So the remainder when divided by (x² - 4x + 3) is in the form ax + b.
Q3
Dividing by (3x - 4) is the same as dividing by (3(x - 4/3) ).
So (x³ + 9x - 14) ÷ (3x - 4)
= (x³ + 9x - 14) ÷ (3(x - 4/3))
= Quotient + remainder/(3(x - 4/3))
x³ + 9x - 14 = 3(x - 4/3)(quotient) + remainder
So you just need to substitute x = 4/3
f(4/3) = remainder
= (4/3)³ + 9(4/3) - 14
= 10/27
No long division is required
