Question

find the quadratic polynomial with zeros 1/2, 3/2​

Answer 1

Step-by-step explanation:

20. A school decided different types of educational tours for the students of Class IX, 1/12th times the square of the

total number of students planned to visit historical monuments, 7/12th times the number of students planned to visit old

age homes while 15 students decided to teach poor children. If above information is expressed in the form of a

polynomial x2

+ 7x + 15, then

12 12

(a) Write the type of polynomial

(i) cubic (ii) linear (iii) quadratic (iv) Biquadratic

(b) Write the co-efficient of ‘x’ in the polynomial

(i) 9/13 (ii) 7/12 (iii) 11/12 (iv) 1/12

(c) Write the constant term

(i) 1/12 (ii) 11/2 (iii) 7/12 (iv) 15

(d) Value of P(x) at x = 2

(i) 33/2 (ii) 11/2 (iii) 22/3 (iv) 14/3

(e) Value of P(x) at x = – 1

(i) 19/2 (ii) 29/2 (iii) 9/2 (iv) 39/2
