CBSE Class 10 Maths Zeroes and Coefficients

Solution

Sum of the roots of a quadratic polynomial is. 

Solution

x² - 3x + 2

Comparing with ax² + bx + c we get

a = 1, b = -3 and c = 2

Product of the roots is c/a = 2/1 = 2

Product of the roots of the polynomial x² - 3x + 2 is 2. 

Solution

Comparing with ax² + bx + c = 0, we get a = 2, b = −4 and c = 2 In the polynomial 2x² - 4x + 2, the sum of the roots is  = = 2
