Important Questions 10th Maths Exercise 2.4
How do we start division of a polynomial by another polynomial?
To obtain the first term of the quotient, divide the highest degree term of the dividend by the highest degree term of the divisor. Then carry out the division process.
What are the division algorithm for Polymomials?
If p(x) and g(x) are any two polynomials with g(x) ≠ 0, then we can find polynomials q(x) and r(x) such that p(x) = g(x) × q(x) + r(x), where r(x) = 0 or degree of r(x) < degree of g(x). This result is known as the Division Algorithm for polynomials.
What are the linear, quadratic and cubic polynomials?
Polynomials of degrees 1, 2 and 3 are called linear, quadratic and cubic polynomials respectively.
What are the number of zeros for a quadratic or cubic polynomial?
A quadratic polynomial can have at most 2 zeroes and a cubic polynomial can have at most 3 zeroes.
