Question

The sum of roots of quadratic equation 5-7x +3x² is: *

Answer 1

And 7/3

Step-by-step explanation:

Let roots be y and z

y+z=-b/a

a=3

b=-7

c=5

y+z=-(-7)/3

=7/3

yz=c/a

=5/3

Answer 2

Answer: 7

Step-by-step explanation:

x²-(∝+β)x+(∝β)=0

5-7x+3x²=0

3x²-7x+5=0

x²-7/3x+5/3=0

(∝+β)=7/3 (sum of roots)
