add ( x^2 + 2x +5 ) + (3x^2- 3x + 1)?

Question

^2 means squared

Answer 1

For algebra, you have to remember that you can only add like terms.

So first, forget about the parentheses, since you're not doign anything to what's in the parentheses (for example, you aren't squaring it or multiplying it all by two). Then rewrite your equation as:
x^2 + 2x +5 + 3x^2 -3x +1

Now gather all like terms. What that means, is put all the numbers that contain an "x^2" together. And put all the numbers that contain just an x together, or no x at all, and so on.

so you have:
x^2 + 3x^2 + 2x -3x +5 +1
then you can add like terms
4x^2 -1x +6

Answer 2

(x^2 + 2x +5 ) + (3x^2- 3x + 1)
=4x^2-x +6

Answer 3

good the following are the corrections. The others are the finest option. 2) 9x^2 -a million 4) (x - 10)(x + 10) 5) (x + 13)(x + a million) 6) (x - 8)(x - 8) 7) x = 0, x = a million/2 8) x = -8. x = 7 9) 3x2+x-a million 10) -2x2-6x+5 11) (x - 9)(x + 8) 12) x + 9)(x - 8) 13) (2x-3)(2x+ 3) 14) (x - 5) (x - a million)

Answer 4

x^2 +2x + 5 + 3x^2 -3x +1
You need to combine like terms
(x^2 + 3x^2) + (2x - 3x) + (5 + 1)
4x^2 - X + 6

Answer 5

Ok...

x^2 + 2x + 5 + 3x^2 - 3x + 1
Move them around...
x^2 + 3x^2 + 2x - 3x + 5 + 1
Add like terms
4x^2 -x + 6

Answer 6

split up each part and rearrange it...
(x^2 + 3x^2) + (2x - 3x) + (5+1)
then just add them together

4x^2-x+6

you can't go any farther after this, because you can't combine anything else

Answer 7

4x^2 - x + 6

Answer 8

4x^2 - x + 6

Answer 9

4x^2-x+6

Answer 10

4x^2-1x+6
