Question

यदि द्विघात बहुपद g(x)=x2-x+4 के शून्यक B हो तब a+b का मान क्या होगा? ​

Answer 1

SOLUTION

GIVEN

a and b are the zeroes of the polynomial

$\sf{g(x) = {x}^{2} - x + 4 }$

TO DETERMINE

The value of a + b

EVALUATION

The given Quadratic polynomial is

$\sf{g(x) = {x}^{2} - x + 4 }$

Here it is given that a and b are the zeroes of the polynomial

$\sf{g(x) = {x}^{2} - x + 4 }$

Then Sum of the zeroes of zeroes = a + b

$\displaystyle \sf{ = - \frac{Coefficients \: of \: x }{Coefficients \: of \: {x}^{2} } }$

$\displaystyle \sf{ = - \frac{ - 1 }{1} }$$= 1$

FINAL ANSWER

a + b = 1
