Answer the following
1. Which of the following expressions is polynomial?
2. If x = -2 is a root of the polynomial P(x) = -2x4 - 7x3 - 3x2 - tx - 10, then find the value of t.
3.The polynomials P(t) = 4t3 - st2 + 7 and Q(t) = t2 + st + 8 leave the same remainder when divided by (t - 1). Find the value of s.
4. Factorise
(i) x3 – 6x2 + 3x + 10
(ii) 2y3 – 5y2 – 19y + 42
