Question

find two numbers with sum 4 and product 2?in second degree equation
​

Answer 1

Let the numbers be x and y.

Given;

Sum of the numbers is 4

product of the numbers is 2.

To find;

x and y.

Formula to be used;

-b+-√b^2-4ac/2

Solution;

x+y=4

y=4-x

x×y=2

x×4-x=2

4x-x^2=2

-x^2+4x-2

x^2-4x+2.

a=1; b=-4; c=2

X=-b+-√b^2-4ac/2

x=-4+-√(-4^2)-4(1)(2)/2

x=-4+-√(16)-8/2

x=-4+-√8/2

x=-2+-√2

Therefore, the numbers are -2+√2 and -2-√2.
