### the quiz today

man that polynomial`s quiz was harder then i thought , i dont know maybe its just me but yeah . that second last question . the one with the "add 10m on one side of the square and 5m on the other" really confused me, did it confuse anyone else ?

## 5 Comments:

if u want help with that question..

here it is..

it meant..

draw a square.... with x = to the length of it's 4 sides...

then.

it sed add 5 metres to one, and 10 to the other..

then u draw a rectangle to show the extension.

one side of the rectangle's length

must say x+5 which means... u gave that side... 5 more metres..

the same on the other side..

but this time u extended it by 10 metres..

so u say taht the other side is x+10

to get the the area..

u simply multiply the two sides together...

(x+10)(x+5) = x^2 + 10x + 5x + 15

then u simplify..

making it..

x^2 + 15x +15

if im wrong in anyway... please tell me....

I love the assistance that you guys are giving each other. Amazingly accurate explanation, but you are wrong in one way...the final answer. (x+10)(x+5)= x^2+15x+50. Hopefully this was just a typo and you have it correct on your test paper.

ohhh poopy......i did that one wrong......i knew it......oh well...its already done and yeah...=/...XD

ooopss i did it wrong to but it also confuse me michelle h.i think i didnt simplify it my answer is likr arvin's answer
