Question

Can someone tell me how to factor a trinomial???

Answer 1

you cant

Answer 2

Yes you can

Answer 3

can you give me an equation

Answer 4

X^2-8x-20

Answer 5

im wrong im sorry

Answer 6

Its iight

Answer 7

Can you help me?

Answer 8

(x + 2) • (x - 10)

Answer 9

yea i can Step-1 : Multiply the coefficient of the first term by the constant 1 • -20 = -20

Step-2 : Find two factors of -20 whose sum equals the coefficient of the middle term, which is -8 .

-20 + 1 = -19
-10 + 2 = -8 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -10 and 2
x2 - 10x + 2x - 20

Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-10)
Add up the last 2 terms, pulling out common factors :
2 • (x-10)
Step-5 : Add up the four terms of step 4 :
(x+2) • (x-10)
Which is the desired factorization
