Question

Find 2 number with sum is 4 and prouct is 2? step by step ​

Answer 1

Answer

Let the numbers be x and y

sum is given as 4 do x+y=4

product is given as 2 so xy=2

x=4-y substitute this is equation 2

which will be equal to y(4-y)=2

4y-y^2=2

4y-y^2-2=0

we must arrange the term first which has the highest degree

so -y^2+4y-2

 so y will be equal to 4.449

substitute this in equation 1

x=4-4.449

then y = -0.449 therefore x and y are 4.449 and -0.449 respectively
