Question

The expression 11x² - 12x - 10 has ___ terms and a constant of ___.

12, 11

3, -10

3, 10

11, 12

Answer 1

ax^2 + bx + c
where c is your constant.

terms, something like 5x^3 + 4x^2 + 3x + 5 has 4 terms
something like 4x^2 + 3x + 5 has 3 terms.
so which one is it?

Answer 2

@shamil98 Is it C ?

Answer 3

10 is my constant right?

Answer 4

11x² - 12x - 10
is that a positive 10 or a negative 10?

Answer 5

It's a positive right? Or am I missing something?

Answer 6

That is a NEGATIVE 10
-10

Answer 7

just like how
x^2 + 5x - 6 , the constant is a negative 6

Answer 8

I can't believe I miss read that. I thought that was a subtraction sign, my bad :(

Answer 9

algebra can be confusing with the minus signs.
but remember you can write this as
11x² + -12x + -10

Answer 10

@phi That makes sense. That is clearly a negative 10. Thanks.

Answer 11

It is a subtraction sign. But it is better to always add negative numbers (to keep things more clear)

so a- b becomes
a + -b
means the something, but the minus sign with the "b" is less confusing.

Answer 12

it helps when you distribute:

2 -3(a+b)
is better written
2 + -3(a+b)
so it is more clear you distribute the -3 times each thing in side the parens
2 + -3a + -3b
(though it is easier to write 2 -3a -3b at the end)

Answer 13

Okay, I think I get it now. Thanks for showing me @phi
