Quadratic Equation -
x² - 11x + 24 = 0
Numbers -
3 & 8
Step-by-step explanation:
QUESTION :-
Divide 11 into 2 parts, so that their product will be 24.
_____________________
SOLUTION :-
Let,
The two parts as x and y respectively.
So,
x + y = 11
=> y = 11 - x
Now,
product of numbers = 24
=> x × y = 24
=> x × (11 - x) = 24
=> 11x - x² = 24
=> - x² + 11x - 24 = 0
So,
The quadratic equation is - x² + 11x - 24 = 0
You can multiply it by (-1), you will get the equation as -
x² - 11x + 24 = 0
In both cases, value of x will be same.

Valuation of two numbers :-
We will solve equation by factorisation method.
x² - 11x + 24 = 0
=> x² - 8x - 3x + 24 = 0
=> x(x - 8) - 3(x - 8) = 0
=> (x - 8)(x - 3) = 0
So,
two numbers are,
x - 8 = 0
=> x = 8
And,
x - 3 = 0
=> x = 3
So,
Numbers are 3 & 8.
