add or subtract the polynomial [9x+4]+6x+4]​

Sagot :

Answer:

[9x + 4] = 9x + 4

[6x + 4] = 6x + 4

we can add the two polynomials:

(9x + 4) + (6x + 4) = 9x + 6x + 4 + 4

= 15x + 8

the result of adding the polynomials [9x + 4] and [6x + 4] is:

15x + 8.

ADDING AND SUBTRACTING SIMPLE POLYNOMIALS

Answer:

The answer is 15x + 8 and 3x.

Step-by-step explanation:

ADDITION:

[tex]9x + 4 \\ + \: 6x + 4 \\ = \: 9x + 6x \: = \: 15x \\ 4 + 4 = 8 \\ \\ 15x + 8[/tex]

SUBTRACTION:

9x + 4 - 6x + 4

= 9x - 6x = 3x

= 4 - 4 = 0

= 3x

Therefore, the correct answer can be 15x + 8 for addition while for subtraction is 3x.
