Question

st of the roots of 2
+ 10r - 5 = 0.
(4) Write the sum and the product of the roots of​

Answer 1

Answer:

I think the equation should be like this

2r square+10r-5=0.So,

by the rules of the quadratic equations

ax square+bx+c=0

sum of the roots is equal to -b/a

product of the roots is equal to c/a

here, a=2,b=10,c=-5 & x=r

so,

sum of the roots = -b/a= -10/2= -5

product of the roots = c/a= -5/2
