When dealing with numbers, we find the LCM by factoring the numbers, and then choosing all the primes appearing, with the highest exponent possible.

Similarly, we will factor the polynomials first:

x^4+3x^3 = x^3(x+3)

x^2-9 = (x+3)(x-3)

x^3+6x^2+9x = x(x^2+6x+9) = x(x+3)^2

The following factors emerged:

  • x,\ x^3 We will choose x^3 because it has the higher exponent
  • x-3
  • x+3,\ (x+3)^2 We will choose (x+3)^2 because it has the higher exponent.

So, the LCM is

x^3(x-3)(x+3)^2

Answer:

£2,121.8

Step-by-step explanation:

Given the following;

Principal P = £2000

Rate r = 3%

Time t = 2 years

n = 1 (time of compounding)

Using the compound interest formula;

A = P(1+r)^t

A = 2000(1+0.03)^2

A = 2000(1.03)^2

A = 2000(1.0609)

A = 2,121.8

hence the amount that will be in his account after 2 years is £2,121.8
