Question

Find the numbers in AP whose sum is 15 and product is -375​

Answer 1

Step-by-step explanation:

hey mate here is your answer:

let,the two numbers in A.P be a-d,a+d

given,

sum of two numbers =15

product of two numbers= -375

solution,

sum of the numbers =15

a-d+a+d=15

2a=15

a=15/2

product of the numbers = -375

(a-d) (a+d)= -375

a^2-d^2 = -375

(15/2)^2-d^2 = -375

225/4+375 = d^2

d^2=43875/100

d=20

Answer 2

Answer:

sup!!

Step-by-step explanation

let,the two numbers in A.P be a-d,a+d

given,

sum of two numbers =15

product of two numbers= -375

solution,

sum of the numbers =15

a-d+a+d=15

2a=15

a=15/2

product of the numbers = -375

(a-d) (a+d)= -375

a^2-d^2 = -375

(15/2)^2-d^2 = -375

225/4+375 = d^2

d^2=43875/100

d=20
