Question

g(x)=x^2-(a+b)x+ab, For which value of x will g (x) = 0?​

Answer 1

Answer:

a and b

Step-by-step explanation:

the given polynomial is in the form of a general quaratic polynomial in which

x² - (α+β)x + αβ= 0

so

when we compare

a = α and b = β

and as we know

α and β are zeroes of quadratic polynomial

so the values for which the given polynomial will be 0 are a and b

Answer 2

Step-by-step explanation:

g(x)=^2-(a+b)x+ab

x^2-ax-bx+ab=0

x(x-a)-b(x-a)=0

(x-a)(x-b)=0

either x=a or x=b

g(a)=0 andg(b)=0
