Factor this expression x^2+9x+20. show your work

You must remember that a polynomial is written like so...

ax^2 + bx + c

In this case...

a = 1

b = 9

c = 20

To factor you must find two numbers who both add up to b (9) AND multiply to c (20)

5 + 4 = 9

5 * 4 = 20

so...

(x + 5)(x + 4)

Hope this helped!

For this case we must factor the following expression:

To do this, we must find two numbers that, when multiplied, result in 20 and when added together, result is obtained 9. These numbers are 5 and 4.

So we have to express the expression as:

answer: what if i dont want to show my work boi.

step-by-step explanation: im watching dbz and eating popcorn leave meh alone

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
