Answers

Answer 1
Answer:

Answer:

x^2+9x -8

Step-by-step explanation:

(12x^2+8x-3)-(11x^2-x+5)

12x^2+8x-3-11x^2+x-5

x^2+9x -8
Answer 2
Answer:

Answer:

x^2 + 9x  - 8

Step-by-step explanation:

Break the brackets out and you will get:

(12x^2+8x-3)-(11x^2-x+5)

= 12x^2 + 8x -3 - 11x^2 - (-x) - (+5)

= 12x^2 + 8x - 3 - 11x^2 + x - 5

=12x^2 - 11x^2 + 8x + x - 5 - 3

= x^2 + 9x  - 8 or x(x+9) -8

You can factorize it even more but it won't factorize much so you can keep it as this equation!

Hope this helped :3
