Question

write the sum
and the product of the roots of 2x+10x-5=0​

Answer 1

Answer:

let the two roots be alpha and beta

comparing it with std eqn we get

a= 2 , b= 10 , c= -5

alpha + beta = -b/a = -10/2 = -5

alpha × beta = c/a = -5/2 = - 2.5

hope it helps...

Answer 2

Answer:

Sum is -5 and product is -2.5
