Question

The sum of three numbers of ap is -3 and their product is 8. Find number.

Answer 1

Answer:

Sum of three number first number is -3

And product =8

Step-by-step explanation:

8-3=5

Hence, the other number is 5

Answer 2

Let the numbers be a-d, a and a+d

$a - d + a + a + d = - 3$

$3a = - 3$

$a = - 1$

Now,

$(a - d)(a + d)a = 8$

$( {a}^{2} - {d}^{2} )a = 8$

$(1 - {d}^{2} ) (- 1) = 8$

$- 1 + {d}^{2} = 8$

${d}^{2} = 9$

$d = + - 3$

Now, when d= 3

Numbers are -4,-1 and 2

When d= -3

Numbers are 2,-1 and -4
