Question

Consider two consecutive even numbers. If one number is x what will the other? Product of these two numbers is 120 .find the numbers and form a second degree equation

Answer 1

Answer:

Let the two even no.s be a & a+2

Given, the product of these no.s is 120.

⇒a(a+2)=120

⇒a 2 +2a−120=0-Equation 1

So, Equation 1 is the quadratic equation in a.
