Identify polynomials in the following:
`g(x)=2x^3-3x^2+sqrtx-1`
If x = 0 and x = −1 are the roots of the polynomial f(x) =2x3 − 3x2 + ax + b, find the value of a and b.
In each of the following, using the remainder theorem, find the remainder when f(x) is divided by g(x) and verify the result by actual division: (1−8)
f(x) = x3 + 4x2 − 3x + 10, g(x) = x + 4
f(x) = 2x4 − 6x3 + 2x2 − x + 2, g(x) = x + 2
The polynomials ax3 + 3x2 − 3 and 2x3 − 5x + a when divided by (x − 4) leave the remainders R1 and R2 respectively. Find the values of the following cases, if 2R1 − R2 = 0.
f(x) = 3x4 + 17x3 + 9x2 − 7x − 10; g(x) = x + 5
