Question

x^2-5x+2=0 sum and product

Answer 1

x^2-5x+2=0 is in the form ax^2+bx+c=0 .

ax^2+bx+c=0 , the sum of the -b/a and the product of the roots is c/a.

where x^2-5x+2=0,

a= 1

b= -5

c= 2

the sum of the roots is -b/a,

-b/a = -(-5)/1

=5

the product of the roots is c/a,

c/a = 2/1

=2

hence the sum = 5 and product = 2.
