Algebra 1 help

Answer 1

ists 2x squared and 5x squared

Answer 2

you can use ^ to show exponents
-14+2x^2 -3x + 5x^2 + 6-6x

better use the equation editor
\[ -14+2x^2 -3x + 5x^2 + 6-6x \]

Answer 3

when adding you can change the order so you could write it like this
\[ 5x^2 + 2x^2 -3x-6x-14+6 \]

Answer 4

it should be clear what -14+6 is

for the x^2 terms: if you have 5 x^2 terms and add 2 more x^2 terms, how many x^2 terms do you have ?

Answer 5

-8

Answer 6

and \[x ^{2}\]

Answer 7

if you have 5 x^2 terms and add 2 more x^2 terms, how many x^2 terms do you have ?

Answer 8

if you think of x^2 as a "thing" and you have 5 of them and add 2 more, how many do you have ?

Answer 9

7 x \[7x ^{2}\]

Answer 10

yes 7 x^2
so far you have
\[ 7x^2 -3x-6x-8 \]
now how many of the x's

Answer 11

2 x's because 3x and 6x right

Answer 12

it is -3x -6x
we could "factor out" the x to get (-3-6) x
now what is -3-6 ?

Answer 13

3

Answer 14

is the 6 a negative too

Answer 15

if the six is negative it be -9 right

Answer 16

yes -3-6 is -9 so the answer is -9x
the whole answer is
\[ 7x^2 -9x-8 \]
