Question

PLEASE HELPPP!!!!Add or subtract show your work for each problem by using boxes circles colored underlined or group in to identify the like terms before you simplify. a.(-2x^2-4x+13)+(12x^2+2x-25)

b.(7x^2+4x-26)-(-7x^2-3x+15)

Answer 1

(a)
`10x^2+2x-12`

(b)
`14x^2+7x-41`

Step-by-step explanation :

Part a:

The given expression is:

`(-2x^2-4x+13)+(12x^2+2x-25)`

First we have to open the brackets.

`-2x^2-4x+13+12x^2+2x-25`

Now adding or subtracting like terms like (x², x and number)

`10x^2+2x-12`

Part b:

The given expression is:

`(7x^2+4x-26)-(-7x^2-3x+15)`

First we have to open the brackets.

`7x^2+4x-26-+7x^2+3x-15`

Now adding or subtracting like terms like (x², x and number)

`14x^2+7x-41`
