Question

Can someone explain how you can use the distributive property to check the binomial factors when a trinomial has been factored. Include an example in your explanation.

Answer 1

help? @nikato

Answer 2

something's wrong. you're supposed to show your tongue

Answer 3

??? @sourwing

Answer 4

u can look at this really old post

Answer 5

i went to look but i can't see the picture someone posted? i took a look at the site, do you know what i could put for this question from that site? @nikato

Answer 6

Im not sure waht to really put but this is what the person drew.

x^2+6x+8
factored
(x+2)(x+3)

Answer 7

ok maybe i can put that instead then, thanks. @nikato

Answer 8

oops i meant x+4 for the second

so distribute
x(x+4)+2(x+4)
so
x^2+4x+2x+8
combine like terms
X^2 +6x+8

Answer 9

okay thank you, do you mind helping me with 2 more if you can? @nikato

Answer 10

ok. i can try

Answer 11

Bo factored x2 – 10xy + 16y2 as follows: ( the image i put )

Did Bo correctly factor the polynomial? Justify your response by explaining why it is is factored correctly or by showing the correct solution if it is not factored correctly.
Explain how you would know if a polynomial of the form ax2 + bxy + cy2 was prime? @nikato

Answer 12

no. the 3rd line should be

x(x-8y)-2y(x-8y)
so the 4th iline should be (x-2y)(x-8y)

Answer 13

for the first question?? @nikato

Answer 14

yes. first question. not sure about the 2nd
