Question

48. If one root of ax²+bx+c=0 is zero, find the value of c
​

Answer 1

if 0 is one root of the polynomial.

then , by formula

$\alpha \times \beta = c$

here alpha & beta are roots of the given polynomial.

let , 0 be alpha .

by equation ,

x² + (sum of zeroes)x + (product of zeroes)

$0 \times \beta = c \\ 0 = c$

hence the value of c is 0.
