Find a thrid degree polynomial equation with rational coeffcients that has roots -4 and 6 +i
neonofarm [45]
For the coefficients to be rational, any complex roots must occur in conjugate pairs. So if 6+i is a root, then so must be 6-i.

Now such a third degree polynomial might be

(x+4)(x-(6+i))(x-(6-i))=(x+4)(x^2-12x+37)=x^3-8x^2-11x+148

The only variation to this would be multiplying throughout by some non-zero constant. This doesn't change the roots.

13. If 6 times the 6th term of an A.P. is equal to
romanna [79]

Answer:

see explanation

Step-by-step explanation:

The n th term of an AP is

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given

6(a₁ + 5d) = 13(a₁ + 12d) ← distribute parenthesis on both sides

6a₁ + 30d = 13a₁ + 156d ( subtract 13a₁ from both sides )

- 7a₁ + 30d = 156d ( subtract 30d from both sides )

- 7a₁ = 126d ( divide both sides by - 7 )

a₁ = - 18d

Now

a₁₉ = a₁ + 18d = - 18d + 18d = 0 ← as required
