Question

Can someone simplify this and also tell me how they did it? (6x^2 - 5) - (3x^2 + x + 7)

Answer 1

what does - (3x^2 + x + 7)=
- 3x^2 - x - 7
you saw how i distributed the negative sign?

Answer 2

yea

Answer 3

(6x^2 - 5) - (3x^2 + x + 7)=
(6x^2 - 5) - 3x^2 - x - 7 : i just replaced it back
6x^2 - 5 - 3x^2 - x - 7 : I took down the first parentheses because I'm not multiplying anything out

Answer 4

add subtract to simplify

Answer 5

so wahst the final product?

Answer 6

6x^2 - 3x^2 - 5 - 7 - x
add/subtract like terms.

Answer 7

(6x^2 - 5) (-3x^2 - x - 7) i got it to that but what do i do with the x that has no exponent when i combine like terms since it has none?

Answer 8

last step is
\[3x^2-x-12\]

Answer 9

you leave it out because it donesn't have a like term.
