Question

find the sum and product of zeroes of px=2(x2-1)+3x-9.

Answer 1

aloha user!!

__________________________

2(x^2 - 1 ) + 3x -9 = 0
2x^2 - 2 + 3x - 9 = 0
2x^2 + 3x -11 = 0


we get this equation:

2x^2 + 3x -11 = 0

we know that the product of zeroes is : αβ = c/a
the product =  -11/2

we know that the sum of zeroes is α + β = -b/a 
the sum= -3/2
