Questions
Check whether the first polynomial is a factor of the second polynomial by dividing the second polynomial by the first polynomial.
t2 – 3, 2t4 + 3t3 – 2t2 – 9t – 12
Check whether the first polynomial is a factor of the second polynomial by applying the division algorithm:
g(t) = t2 – 3, f(t) = 2t4 + 3t3 – 2t2 – 9t – 12

Solution
t2 – 3, 2t4 + 3t3 – 2t2 – 9t – 12
t2 – 3 = t2 + 0.t – 3
2t2 + 3t + 4
`t^2 + 0.t - 3")"overline(2t^4 + 3t^3 - 2t^2 - 9t - 12)`
2t4 + 0.t3 – 6t2
– – +
3t3 + 4t2 – 9t – 12
3t3 + 0.t2 – 9t
– – +
4r2 + 0.t – 12
4t2 + 0.t – 12
– – +
0
Since the remainder is 0.
Hence, t2 – 3 is a factor of 2t4 + 3t3 – 2t2 – 9t – 12.
