WebFinding sum of zeroes: Sum of zeroes = (5-3√2)+(5+3√2) Sum of zeroes = 5+5 = 10. Finding product of zeroes: Product of zeroes = (5-3√2)(5+3√2) We know that a 2-b 2 = (a+b)(a-b). Hence, (5) 2 – (3√2) 2 = (5-3√2)(5+3√2). Therefore, product of zeroes = 25 – [9(2)]= 25 – 18 = 7. Thus, the required quadratic polynomial is: P(x ... WebProduct of zeroes = αβ = 1. ∴ If α and β are zeroes of any quadratic polynomial, then the quadratic polynomial equation can be written directly as. x2– (α+β)x+αβ = 0. x2–4x+1 = 0. Thus, x2–4x+1 is the quadratic polynomial. Exercise 2.2 of NCERT solutions for Class 10 Maths Chapter 2 is the second exercise of Polynomials of Class ...
WebZeros and multiplicity. When a linear factor occurs multiple times in the factorization of a polynomial, that gives the related zero multiplicity. For example, in the polynomial f (x)= (x-1) (x-4)^\purpleC {2} f (x) = (x −1)(x −4)2, the number 4 4 is a zero of multiplicity \purpleC {2} 2. Notice that when we expand f (x) f (x), the factor ... WebThe polynomial. ( x − α) ( x − β) is zero precisely when x = α or x = β. Multiply this out and see if α + β or α β appear somewhere prominently (and can be replaced with − 1 3 and 4 ). Share.
