So, the number of zeroes is 0. So, the number of zeroes is 1. So, the number of zeroes is 3. So, the number of zeroes is 2. So, the number of zeroes is 4. Concept insight: Since the polynomial p x given here is a polynomial in variable x, so to find the number of zeroes, we look at the number of points where the graph intersects or touches the x-axis and not the y-axis.
Concept insight: The zero of a polynomial is that value of the variable which when substituted in the polynomial makes its value 0. When a quadratic polynomial is equated to 0, then the values of the variable obtained are the zeroes of that polynomial.
The relationship between the zeroes of a quadratic polynomial with its coefficients is very important. Also, while verifying the above relationships, be careful about the signs of the coefficients. Concept insight: Since the sum and product of zeroes gives 2 relations between three unknowns so we assign a value to the variable a and obtain other values.
In the process of division, be careful about the signs of the coefficients of the terms of the polynomials. Concept insight: Remember that if x - a and x - b are factors of a polynomial, then x - a x - b will also be a factor of that polynomial. Also, if a is a zero of a polynomial p x , where degree of p x is greater than 1, then x - a will be a factor of p x , that is when p x is divided by x - a , then the remainder obtained will be 0 and the quotient will be a factor of the polynomial p x.
To cross check your answer number of zeroes of the polynomial will be less than or equal to the degree of the polynomial. Concept insight: In order to answer such type of questions, one should remember the division algorithm. Also, remember the condition on the remainder polynomial r x. The polynomial r x is either 0 or its degree is strictly less than g x.
The answer may not be unique in all the cases because there can be multiple polynomials which satisfies the given conditions. Thus, the relationship between the zeroes and the coefficients is verified. Concept insight: The zero of a polynomial is that value of the variable which makes the polynomial 0. Remember that there are three relationships between the zeroes of a cubic polynomial and its coefficients which involve the sum of zeroes, product of all zeroes and the product of zeroes taken two at a time.
Concept insight: A cubic polynomial involves four unknowns and we have three relations involving these unknowns, so the coefficients of the cubic Ncert Solutions For Class 10th Information Technology Kit polynomial can be found by assuming the value of one unknown and then finding the other three unknowns from the three relations.
Concept insight: When the polynomial and its zeroes are given then, Ncert Solutions Class 10th Polynomials World remember to apply relationships between the zeroes and coefficients. These relations involve the sum of the zeroes, product of zeroes and the product of zeroes taken two at a time.
For finding the remaining zeroes of the given polynomial, we will carry out the division of Hence, 7 and -5 are also zeroes of the given polynomial. Concept insight: If a is a zero of a polynomial p x , where degree of p x is greater than 1, then x - a will be a factor of p x that is when p x is divided by x - a , then the remainder obtained will be 0 and the quotient will be a factor of p x using division algorithm.
