The difference between two numbers is 20. their sum is 14.find the numbers

sladkih [1.3K]

Let the two numbers be x and y. The sum of x and y is 14 and the difference is 20. We can write a system of equations and solve:

$x-y=20 \\
x+y=14 \\
2x=34 \\
x=17$

Then substitute x back into one of the equations to find y:

$x+y=14 \\
17+y=14 \\
y=-3$

So the two numbers are 17 and -3

Evgesh-ka [11]

5x³ + 30x² + 15x

Take out a common factor of 5x : 5x (x² + 6x + 3)

The factors of the quadratic portion are [ x - (-3 + √6) ] and [ x - (-3 - √6) ].

So finally, we wind up with:

<em>5x (x + 3 - √6) (x + 3 + √6) .</em>
