Step-by-step explanation:

Answer 2

convert in quadratic equation :

"The difference of two numbers is 3 and their product is 270"

Given:

The difference of two numbers is 3 and their product is 270.

To find:

Represent the given situation in the quadratic equation.

Solution:

Let one number is x

and other number is y

According to the condition

• x-y = 3 --------------------(I)
• xy = 270 ---------------(II)

from the first equation

• x = 3+y

put the value of x in (II) equation

• xy = 270
• (3+y)y = 270
• 3y + y² = 270
• y²+3y-270 = 0

The quadratic equation is y²+3y-270 = 0
