Question

2) Find the zeroes of 4x2 -5x -9.also verify the relationship.​

Answer 1

Answer:

4x2 -5x-9

4x2-9x-4x-9

x(4x-9) 1(4x-9)

(x+1) (4x-9)

therefore the zeros are:

x+1=0. 4x-9=0

x= -1. x=9/4

alpha=-1. bita=9/4

by comparing 4x2-5x-9,

a=4 ,b=-5, C= -9

alpha + bita = -1+9 /4

=5/4

-b/a =-(-5)/4

=5/4

alpha * bit a =-1*9/4

=-9/4

-b/a=-9/4

hence proved
