Question

Q1. Write an example of an algebraic expression that is not a polynomial. Q2. p(x) = √ 3 + 1 is not a polynomial. Give reason
Q3. . Find the value of polynomial 8x³ - 6x² +2 at x = 1
Q4. If p(x) = 6x3 + 5x2 – 3x + 2 find p(-1)
Q5. Find the zero of the polynomial p(y) = 2y + 7
Q6. Find whether xn + yn is divisible by x – y( y≠0) or not.

Answer 1

Q 1.2×^1÷2+1
Q2. because the power should not be inverse
Q3. 8x(1)3-6x (1)2+2=8x+6x+2=14x+2
Q4. -6+5+3+2=4
Q5. 2y+7=0
2y=-7 y=-7÷2

Answer 2

ans1
if you write any variable of polynomial in negative integer or in real number s power then it will not cosider in polynomial
