if -2 and 3 are the zeroes of the polynomial ax2+bx-6 then find the value of a and b​

1 thought on “if -2 and 3 are the zeroes of the polynomial ax2+bx-6 then find the value of a and b​”

1. Step-by-step explanation:

   Given:-

   polynomial. f(x)= ax^2+bx-6

   zeroes are -2 and 3

   value of a and b=?

   solution:-

   f(-2)=4a-2b-6=0

   4a-2b=6. (1)

   f(3)=9a+3b-6=0

   9a+3b=6. (2)

   solving (1) and (2)

   3*(1)+2*(2)

   12a-6b=18

   +18a+6b=12

   a= 1

   b= -1
