Given :

• x² + 7x + 10 = 0

To Find :

• Sum of the root
• Product of the root

Solution :

Let, a = 1, b = 7 & c = 10

We know that,

• Sum of the root = - b/a

Substituting the value of b & a,

- 7/1 = - 7

∴ Sum of the root = - 7

We also know that,

• Product of the root = c/a

Substituting the value of c & a,

10/1 = 10

∴ Product of the root = 10

Answer:

Sum of the roots = -b / a:

-7 / 1 = -7

Product of the roots = c /a:

10 / 1 = 10
