Question

can sumbody explain how to do this problem :

2a^2 + 30a + 100

Answer 1

You haven't stated anything to do... do you want to factor it?

Answer 2

o sorry yes

Answer 3

help - the quadratic is very very important. You want to do science, engineering, finance, stocks & shares, be an astronaut learn this!

Answer 4

........ and many more things

Answer 5

Umm @T0mmy what are you talking about

Answer 6

Mmmmmm - ya seem savvy enough to get on this site with the pseudonym help123456 to know a little about how passwords and usernames work. Computers: devised and invented by mathematicians,

Answer 7

Ok, what do you want to do with this quadratic?

Answer 8

factor it and what are you talking about

Answer 9

OK: x=-5 OR x=-10

You have the answer but know nothing

Answer 10

wait what ik the answer but i get lost doing it

Answer 11

Ok, no problem show me your working and I'll see if I can help.

Answer 12

ok but i had to type it so yeah:

To do this problem you would approach it in a different way. First instead of finding the two numbers that add to give you the middle number and the last number by multiplying, you see the two in the front of the equation you now have to set it up differently now you have to set it up like this (2a + ) (a + ). You must find a number times 2 times that fits into the equation to get 100.
Step 2) So you find that 10 and 10 will do because 2 times 10 +10 equals 30.

Answer 13

Yes or simply it by dividing everything by 2

To get: \[a ^{2}+15x+50\]

Answer 14

o that seems easy so then what...

Answer 15

You've answered it, what multiplies to get 50?

Answer 16

10 *5 50*1

Answer 17

To be precise 25x2 as well. Which one of the 3 add to 15?

Answer 18

nun

Answer 19

What I meant was which of (1,50)or(2,25)or(10,5) sum to 15.

Answer 20

nun right

Answer 21

well 10+5=15...I think
anyway you've got the answer adios
