Question

find the zeroes of following quadratic polynomial and verify the relationship between zeroes and coefficients p(x)=2x^2-3x-9​

Answer 1

Answer:

2x^2-3x-9

2x^2-6x+3x-9

2x(x-3)3(x-3)

2x+3=0

x-3=0

therefore the zeroes are 3 and -3/2

alpha + beta = -B/a=co efficient of x/ x^2

alpha× beta= c/a=constant term / coefficient of x^2
